G'day Cody Fendant,

Yes, I can make that silently fail too: 

$ perl -e '$result = `foobar`'

But I start getting feedback if I ask for it (i.e. with strict and warnings): 

$ perl -Mstrict -Mwarnings -e '$result = `foobar`'
Global symbol "$result" requires explicit package name at -e line 1.
Execution of -e aborted due to compilation errors.

OK, let's fix up that one from strict:

$ perl -Mstrict -Mwarnings -e 'my $result = `foobar`'
Can't exec "foobar": No such file or directory at -e line 1.

[download]

Now this one from warnings which clears all errors:

$ perl -Mstrict -Mwarnings -e 'my $result = `ls`'

Given you're working in a CGI environment, you may find the fatalsToBrowser feature of CGI::Carp to be useful.
