      When executing a CGI process, the <code>PATH_INFO</code> variable is now
      always set to the empty string or a value starting with a <code>/</code> character,
      as required by RFC 3875. It was previously possible for some combinations of
      <a href="/pkg/net/http/cgi#Handler.Root"><code>Handler.Root</code></a>

\\   U+005C backslash
\'   U+0027 single quote  (valid escape only within rune literals)
\"   U+0022 double quote  (valid escape only within string literals)
</pre>

<p>
All other sequences starting with a backslash are illegal inside rune literals.

<pre class="ebnf">
rune_lit         = "'" ( unicode_value | byte_value ) "'" .
unicode_value    = unicode_char | little_u_value | big_u_value | escaped_char .

<p>
Most hand-written assembly files do not include the full package path
in symbol names, because the linker inserts the package path of the current
object file at the beginning of any name starting with a period:
in an assembly source file within the math/rand package implementation,
the package's Int function can be referred to as <code>·Int</code>.

<code>iota</code> represents successive untyped integer <a href="#Constants">
constants</a>. Its value is the index of the respective <a href="#ConstSpec">ConstSpec</a>
in that constant declaration, starting at zero.
It can be used to construct a set of related constants:

const (
	c0 = iota  // c0 == 0
	c1 = iota  // c1 == 1
	c2 = iota  // c2 == 2
)
