You’re absolutely right, of course. In my defence, that slide is in the 5.10 section, so the code does work.

But I should reverse the order of the operands in all of those examples.

Thanks.

Slide 24 of 61 Smart Match Examples

In Perl 5.10.0
perl -le ‘@a=(1,2,3); print “found\n” if @a ~~ 2;’
found

perl -le ‘@a=(1,2,3); print “found\n” if 2 ~~ @a;’
found

In Perl 5.10.1 and above:

perl -le ‘@a=(1,2,3); print “found\n” if @a ~~ 2;’
perl -le ‘@a=(1,2,3); print “found\n” if 2 ~~ @a;’
found

You example uses @foo ~~ bar which does not work since 5.10.0. To find scalar in array the array has to be the second.

Hi,

First: thanks for sharing!

Second: I’m very happy to see notices I didn’t know, like the HTTP::Tiny in core, etc too many time without read delta or brew new versions…

Greetings!
