Re^2: Non-destructive array processing

Nearly.

local *array = \@array;

This will work with lexically scoped variables too.

But what will simply alias the lexical `@array` with the dynamical `@array`. So I don't see what you've achieved by doing this. One problem with this that you probably didn't foresee is that lexicals are resolved before dynamic variables. Example: `my @foo = 1..4; local *foo = ['a'..'d']; print @foo; # 1234` [download] The problem is solved through `our()` since that creates an aliased lexical: `my @foo = 1..4; our @foo = 'a'..'d'; print @foo; # abcd` [download] `ihb`	[reply] [d/l] [select]
