Re: How to call a function on each item after a split?by 2teez (Priest)

Please, before one shutdown the wonderful solution first given by aitap above on this issue,
Why use chomp and then sepeartely, remove spaces? At the beginning and endling of each value?
I thought, \s+ also covers \n that chomp is suppose to remove?
I modified the OP clean subroutine and both map and grep gave the happy endling.
So, there is really no need for the extra $_ as perviously stated, if the modified subroutine is considered.
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
