So complicated and ugly!
That's true, of course... but some people just want to
interpolate :) — I have to admit I've also felt that urge at times...
This is probably the outcome of the generalizing behavior of our
brains: we've learnt we can interpolate scalars and arrays, so why not also
hashes, functions, anything? (This behavior, in and of itself, is
certainly a Good Thing, BTW, otherwise we probably wouldn't be where we
are today, messing with Perl... supported by those little silicon chips,
etc.)
Also, some people just find
"abc ${\config('username')} xyz";
easier to read/type than
"abc ".config('username')." xyz";
even though they are exactly the same number of chars.
Anyhow, the nice thing is that with Perl's TIMTOWTDI-ness,
everyone can get happy :)
