in reply to Bareword rules?

print is a bit special, since it expects a file handle as an optional first argument, which can be a bareword.

You can eliminate that speciality by adding an explicit STDOUT:

$ perl -le 'print STDOUT one, two, three' onetwothree

So you can have as many barewords in term position as you like.

If you leave out a comma, you have indirect method call syntax instead:

$ perl -le 'print STDOUT one, two three' Can't locate object method "two" via package "three" (perhaps you forg +ot to load "three"?) at -e line 1.
