Re^3: u+ fails to force scalar context to empty list assignment: +( () = ... )

Interesting!

> Shorter alternative:

Well ...

the sub ctxt() is just using the well documented wantarray the rest is only cosmetics to provide readable output.

If I wanted to golf, I could also do:

>perl -E"sub f{say qw/s l v/[wantarray//'2']};+f;$a=+f;@a=+f"
v
s
l

So your alternatives to `$a = +f()` are magical code and incomprehensible code?	[reply] [d/l]
