Why would I write $name."'s dog" when I can write the much more readable "${name}'s dog" ?
(And last I heard, Perl's concatenation was slightly slower than interpolation anyway, though I care less about that than about concatenation being less readable than interpolation.)

Which of these is more readable is entirely subjective, so you don't have much of a point.

Oh yeah, I forgot, we're talking about Perl here, so nobody cares about readability.

Sorry, but you don't make any sense whatsoever.

Readability is not subjective, because there are testable human norms which exist, and readability is generally concerned with the overall result.

This line of argument misses the point. What I dislike is two competing ways to write the same thing, the other which is not even used but still isn't removed. I used this to illustrate the fact that Perl is backwards compatible to a fault.

yes perl maintains backwards compatibility and many ways to do the same thing.

for some people this is a problem

for other people this is part of the great power of perl and why they love to use it.

but in any case, this shouldn't be news to anyone.
