See perlvar (for 5.10) when there was a section entitled "Technical Note on the Syntax of Variable Names", which contained the paragraph:
Perl identifiers that begin with digits, control characters, or punctuation characters are exempt from the effects of the package declaration and are always forced to be in package main; they are also exempt from strict 'vars' errors.
Seems to have disappeared from later versions.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
