This functionality in this package is mostly captured in the Arena type.
Arenas allocate large chunks of memory for Go values, so they're likely to
be inefficient for allocating only small amounts of small Go values. They're
best used in bulk, on the order of MiB of memory allocated on each use.

Note that by allowing for this limited form of manual memory allocation
that use-after-free bugs are possible with regular Go values. This package

<h4 id="For_condition">For statements with single condition</h4>

<p>
In its simplest form, a "for" statement specifies the repeated execution of
a block as long as a boolean condition evaluates to true.
The condition is evaluated before each iteration.
If the condition is absent, it is equivalent to the boolean value
<code>true</code>.

### New unique package

The new [unique](/pkg/unique) package provides facilities for
canonicalizing values (like "interning" or "hash-consing").

Any value of comparable type may be canonicalized with the new
`Make[T]` function, which produces a reference to a canonical copy of
the value in the form of a `Handle[T]`.
Two `Handle[T]` are equal if and only if the values used to produce the
handles are equal, allowing programs to deduplicate values and reduce

// registers, as in [R1,R3-R5] or [V1.S4, V2.S4, V3.S4, V4.S4].
// For ARM, only R0 through R15 may appear.
// For ARM64, V0 through V31 with arrangement may appear.
//
// For 386/AMD64 register list specifies 4VNNIW-style multi-source operand.
// For range of 4 elements, Intel manual uses "+3" notation, for example:
//
//	VP4DPWSSDS zmm1{k1}{z}, zmm2+3, m128
//
// Given asm line:
//

			// details for all the errors.
			for _, e := range list {
				fmt.Fprintln(os.Stderr, e)
			}
			os.Exit(2)
		}
		fatalf("parsing %s: %s", name, err)
	}
	return ast1
}

func sourceLine(n ast.Node) int {
	return fset.Position(n.Pos()).Line
}

// ParseGo populates f with information learned from the Go source code
// which was read from the named file. It gathers the C preamble

The key is interpreted as a field name for struct literals,
an index for array and slice literals, and a key for map literals.
For map literals, all elements must have a key. It is an error
to specify multiple elements with the same field name or
constant key value. For non-constant map keys, see the section on
<a href="#Order_of_evaluation">evaluation order</a>.

For struct literals the following rules apply:

files:

	x.cgo1.go       # for gc (cmd/compile)
	y.cgo1.go       # for gc
	_cgo_gotypes.go # for gc
	_cgo_import.go  # for gc (if -dynout _cgo_import.go)
	x.cgo2.c        # for gcc
	y.cgo2.c        # for gcc
	_cgo_defun.c    # for gcc (if -gccgo)
	_cgo_export.c   # for gcc
	_cgo_export.h   # for gcc
	_cgo_main.c     # for gcc
	_cgo_flags      # for build tool (if -gccgo)

// for any Go type, but represents the same type for any given function
// invocation.
