Certainly (less special cases make parsing faster). That's documented
in perlvar :

Perl identifiers that begin with digits, control characters, or
punctuation characters are exempt from the effects of the C<package>
declaration and are always forced to be in package C<main>; they are
also exempt from C<strict 'vars'> errors.  A few other names are also
exempt in these ways:

	ENV		STDIN
	INC		STDOUT
	ARGV		STDERR
	ARGVOUT		_
	SIG
