in reply to variable processing and checking in one statement

How about


Have checkFn return the passed data if all is well, or undef if not and have doSthWith check its arguments.

Or, incorporate the check into doSthWith - depending on where you want to localize the knowledge about the condition, and how you want to handle the race between the check and what you do with $test

And, I don't advocate this but find the range of possibilities interesting and can't seem to stop myself from updating:

sub { doSthWith($_[0]) if(checkFn($_[0])); }->($test);
