Re^2: avoiding hash key typos

Yep, you sure do.

Im thinking more along the lines of when a hash key is supposed to be used in more than one place in a script and it is misspelled in one or more of them.

Note that that error is not directly because the hash key is invalid. This would produce the same error: `my $c = undef; print "$c\n";` [download] Anon's sample only emits a warning because it's using the bad value for something that doesn't accept undef's... but if you were doing something like the following, you would get silent failure/undesired results: `my $ct = $dbh->selectrow_array("SELECT ... WHERE x = ?",{},$c);` [download]	[reply] [d/l] [select]
