Hello davies,

> It seems to me to be inelegant to repeat undef

No, is not. Compiler does not bother with elegance ;)

Anyway I suspect you cannot avoid them repeated: you are are in left side of an assignement, and inside a my declaration: no array (well you mean list?) can be there.

PS

An eventual list as second (or whatever..) element in the assignement will slurp everything

perl -e "$str = 'a b c d e f g';@arr=(1,2,3,4,5); ($key, @arr, $val) = + split(/\s+/, $str); print qq($key $val\n@arr\n)" a b c d e f g # even if the array is presized: perl -e "$str = 'a b c d e f g';$#arr=4; ($key, @arr, $val) = split(/\ +s+/, $str); print qq($key $val\n@arr\n)" a b c d e f g

L*

There are no rules, there are no thumbs..
