in reply to select * and bind_cols considered harmful
in thread Perl Programming guidelines/rules

Sorry, but I'm flabbergasted that anyone would ever use "select *" in a real program! That is the bug waiting to happen, not bind_cols.

I think typing out the list of lexical variables is worth the extra speed. There is some data on the speed difference in Tim Bunce's talk.

Of course, if speed makes no difference in your application then use whatever you like.
