Re: use constant usage clarification

[this]' gives a scalar assignment error use constant x = 1/3

Really? Cos when I try it, the error is: Unquoted string "x" may clash with future reserved word.

Care to post a short script that produces that error when run?

perl -MConfig -e "BEGIN{print 'Perl ', map {$Config{$_},' '}qw/version
