Its type must be a <a href="#Type_definitions">defined</a> type <code>T</code> or a
pointer to a defined type <code>T</code>. <code>T</code> is called the receiver
<i>base type</i>. A receiver base type cannot be a pointer or interface type and
it must be defined in the same package as the method.
The method is said to be <i>bound</i> to its receiver base type and the method name

### Iterators

is also treated as implicitly marked <code>NOPTR</code>.
It is not possible to define a symbol containing pointers in an assembly source file;
such a symbol must be defined in a Go source file instead.
Assembly source can still refer to the symbol by name
even without <code>DATA</code> and <code>GLOBL</code> directives.
A good general rule of thumb is to define all non-<code>RODATA</code>
symbols in Go instead of in assembly.

Vendoring in std and cmd
========================

The Go command maintains copies of external packages needed by the
standard library in the src/vendor and src/cmd/vendor directories.

There are two modules, std and cmd, defined in src/go.mod and
src/cmd/go.mod. When a package outside std or cmd is imported
by a package inside std or cmd, the import path is interpreted
as if it had a "vendor/" prefix. For example, within "crypto/tls",
