(Use the -e command line switch, then you can run and test perl syntax entered in the command line.)

You can enable strict and warnings on the command line. That ought to fix it fix it.

perl -cw -Mstrict -e "Welcome Back"
[download]

yields:

-e syntax OK

Oops. It works with a single word:

perl -cw -Mstrict -e Welcome
[download]

Bareword "Welcome" not allowed while "strict subs" in use at -e line 1.
-e had compilation errors.

But with two words, it's problematic:

perl -MO=Deparse -e "Welcome Back"
[download]

produces:

'Back'->Welcome;
-e syntax OK

Syntaxwise, it's OK, even under strict.

This is the so-called indirect object syntax, which often is problematic as it doesn't always work as intended. I wish strict had a way to disallow it.
