[perl #88740] RFE: allow length(undef)=>0 (w/no warnings)
Message ID:

undef in numeric context evaluates to 0, so your example of summing up a
bunch of lengths will still work identically (although the warning that
is generated is now "Use of uninitialized value in addition (+)" instead
of "Use of uninitialized value in length". Also, if you want to suppress
the warning, previously you had to do "(defined($str) && length($str))
|| 0", where now you can do just "length($str) || 0", since passing
undef to length no longer warns. I'm inclined to close this ticket,
unless anyone can see anything here that should be done.
