scalar

See the current Perl documentation for scalar.

Here is our local, out-dated (pre-5.6) version:


scalar - force a scalar context



scalar EXPR



Forces EXPR to be interpreted in scalar context and returns the value of EXPR.

    @counts = ( scalar @a, scalar @b, scalar @c );

There is no equivalent operator to force an expression to be interpolated in list context because it's in practice never needed. If you really wanted to do so, however, you could use the construction @{[ (some expression) ]}, but usually a simple (some expression) suffices.

[perldigious]: Also coincidentally, I'm currently in the middle of a winter storm that has dropped 1 foot of snow and is expected to drop another. I might have to adapt this for customers/vendors who come visit and put it at the beggining of every presentation I give.
[Discipulus]: the photo was removed... Cyrano de Berjerac was not of the same idea..
[stevieb]: perldigious: video near our hq in Montreal. Here in Calgary, it's -28c... we've only got 3" of snow so far, but there are several feet in the mountains already
[perldigious]: Snowshoeing time stevieb? I need to buy a pair so I can walk my German Shepherd properly through the country.
[stevieb]: yeah, I snowshoe a fair amount in the mountains. I also use spikes similar to these very often as well
[perldigious]: Discipulus: alternate link
[stevieb]: LOL you can easily replace "Helsinki" with "Alberta"
