A2P or not 2P

bitman has asked for the wisdom of the Perl Monks concerning the following question:

I converted an Awk to Perl and this line : inok = getline was converted to : $inok = ($_ = &Getline0(),$getline_ok); This appears to be the same as $_ = &Getline0; $inok = $getline_ok; or am I missing some hidden meaning?

    Your assumption is correct.

    In scalar context, a list with parens evaluates to the last element.

    You are right the two statements are equivalent.

    It may seem a little obfuscated but I guess the intention was to replace awk's "var = getline" with a single statement.

[ambrus]: 1nickg: obviously the gamers don't know. but anyway, I need the whole room backlit, because watching a monitor in a dark room (like many people do) is tiring for my eyes, even more so than doing it in a lit room.
[1nickt]: ambrus I agree. I suspect one's eyes are always trying to adjust across the boundary between very bright and very dark ... like a camera's autofocus struggling to choose the target.
