with an unrecognized GODEBUG setting as an invalid program.
Programs with more than one `//go:debug` line for a given setting
are also treated as invalid.
(Older toolchains ignore `//go:debug` directives entirely.)

The defaults that will be compiled into a main package
are reported by the command:

{{raw `
	go list -f '{{.DefaultGODEBUG}}' my/main/package
`}}

<pre>
one, two, three = '一', '二', '三'
</pre>

The <a href="#Blank_identifier">blank identifier</a> provides a way to
ignore right-hand side values in an assignment:
</p>

<pre>
_ = x       // evaluate x but ignore it
x, _ = f()  // evaluate f() but ignore second result value
</pre>

<p>
The assignment proceeds in two phases.
