I'm glad Ovid (++) mentioned the Deparse module, but be aware that different options can affect the output:

# no options: $ perl -MO=Deparse -e 'my @lexlist = @_ or sort keys %lexicon' sort keys %lexicon unless my(@lexlist) = @_; #--- # using -x7 (level 7 expands code into equivelant logical constructs # using &&, ?:, and do{}) -- (giving us back nearly the original) $ perl -MO=Deparse,-x7 -e 'my @lexlist = @_ or sort keys %lexicon' my(@lexlist) = @_ or sort keys %lexicon; #--- # however, using -p (to fully parenthesize) can often help expose # such problems as well: $ perl -MO=Deparse,-p -e 'my @lexlist = @_ or sort keys %lexicon' ((my(@lexlist) = @_) or sort(keys(%lexicon)));

It is sometimes useful to explore the output of Deparse with various options applied.
