Re^4: If you believe in Lists in Scalar Context, Clap your Hands

[moritz]

One could argue that built-ins like map and grep don't return a list in scalar context, but are context sensitives themselves, so they are not fit for explaining "a list in scalar context". Likewise a regex match with /g.

[chromatic]

Sure, but you can also argue that 1, 2, 3, isn't a list of values but a list of expressions. Is this a list:

my $x = ($y = 1), ($z = 2);

How about this?

s{\\}{\\\\}g, print

Or this?

foo => scalar param( 'foo' )

It's difficult to tell without seeing the context... which makes me wonder if lists do exist, or if we should talk about the value of expressions instead.
