Re^3: Using 'keys' on a list (update x2)

> no, list in scalar context returns the last value

That's wrong.

A comma separated list returns the last value in scalar context, otherwise it always depends on the operator.

surrounding a LIST with (...)[-1] is a reliable way to get the last element

  DB<7> x (1..5)[-1]
0  5
  DB<8>

That's wrong. got an example of a "list in scalar context" or "comma operator in scalar context" or whatever that returns something other than the last value? `wantarray` is cheating	[reply] [d/l]
