What makes you think I confuse them?
I show them the idiom as I write it and encourage them to
write it the same way. If the question of whether they
are the same comes up, I just say, "Yeah, they are aliases
for each other, but I like to write them differently
because I think it is clearer that way." I have yet to
see anyone find that a huge hurdle. I have seen getting
used to the different type of looping be a hurdle.
As for telling people things up front, do you think that
up front I tell people that blocks are really hashes, REs
are really done by recursion, or many other minor details
of the language? Perl is a big language, with many
corners, and you shouldn't present it all at once. | [reply] |
