in reply to Stupid mistakes I repeatedly make

My most irritating mistake concerns the use of x, the repetition operator.

my $multiple_Zs = 7 x 'Z'; ##Wrong
instead of
my $multiple_Zs = 'Z' x 7; ##Correct

I'm not sure but I guess this has something to do with that English is not my first language. I think the natives read it as "Z times 7" and then is DWIMs. In Swedish it spoken the other way around. But all in all, this is one of only a few cases where Perl NDWIM.

    I disagree, and being swedish I can do that. :-) Maybe you think like that, but not everyone does. "Times" in swedish, "gånger", is just as commutative as "times". A hypothesis is that one may think like that because that's how one often does it when being taught algebra in school: 7a + 3b = 2c.

    If you don't look at it like multiplication but rather as "repeated ... times" it perhaps would be easier to remember.


    See perltoc if you don't know which perldoc to read!
