Sorry, that should be:
my @column_headers = map trim($_), split /\|/, $header_line;
I'm still relatively new to using BLOCKs within statements like map
and grep and can never remember what is significant when the block
exits. :) In my original post you can see the result of my uncertainty
(especially when the custom sub that I'm calling has an error in it,
not the map call). Once I fixed my 'trim' sub I forgot to revert map.
Using an EXPR with map is even more confusing to me, but it seems to
work here so I'll leave it at that. ;D
