[Cookie] now preserves double quotes surrounding a cookie value.
The new [Cookie.Quoted] field indicates whether the [Cookie.Value]

pkg reflect, method (Value) FieldByIndexErr([]int) (Value, error)

The [SliceAt(typ Type, p unsafe.Pointer, len int)] function
returns a Value representing a slice whose underlying array starts

pkg unique, func Make[$0 comparable]($0) Handle[$0] #62483
pkg unique, method (Handle[$0]) Value() $0 #62483

### 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

behavior has changed based on a non-default value
for that setting.
For example, when `GODEBUG=http2client=0` is set,
`/godebug/non-default-behavior/http2client:events`
counts the number of HTTP transports that the program
has configured without HTTP/2 support.

## Default GODEBUG Values {#default}

When a GODEBUG setting is not listed in the environment variable,
its value is derived from three sources:

The [RuneLen] function returns the number of 16-bit words in
the UTF-16 encoding of the rune. It returns -1 if the rune

pkg runtime/metrics, method (Value) Float64() float64

pkg runtime/metrics, method (Value) Kind() ValueKind
pkg runtime/metrics, method (Value) Uint64() uint64
pkg runtime/metrics, type Description struct
pkg runtime/metrics, type Description struct, Cumulative bool

The new [ParseCookie] function parses a Cookie header value and
returns all the cookies which were set in it. Since the same cookie
name can appear multiple times the returned Values can contain
more than one value for a given key.

The new [ParseSetCookie] function parses a Set-Cookie header value and

The new methods synonymous with the method of the same name
in [Value] are added to [Type]:
1. [Type.OverflowComplex]
2. [Type.OverflowFloat]
3. [Type.OverflowInt]
