Re^10: Does @{ } copy arrays?

Hmm ... as far as I understood dave, copying to an rvalue doesn't help, because the array has already been "prepared" for later modification without taking care about any rvalue context !(?)

so calling with arg @a-1 is always the fastest alternative.

because the array has already been "prepared" for later modification without taking care about any rvalue context ! What? We're talking about a Perl that's fixed to not add the magic for rvalue `$#a`. You said it would be easy to forget `foo($#a)` is an lvalue and that it's a common occurrence. I replied that it's no biggie if it's true. That case can be handled if there is a need.	[reply] [d/l] [select]
