> 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. update surrounding a LIST with `(...)[-1]` is a reliable way to get the last element `DB<7> x (1..5)[-1] 0 5 DB<8>` [download] update see also List's terminology and Parentheses in Perl Examples for "LIST", "list context", "list value", "list assigment", "list operator" Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

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]
