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";` [download] easier to read/type than `"abc ".config('username')." xyz";` [download] 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 :)	[reply] [d/l] [select]

It is in a print, so a comma would be more natural than a dot. There is no need to build a single scalar when the operator takes a list. `print config('username'), " is my username";` [download] Most likely the OP would want a `\n` in there too, but that isn't really part of the interpolation question.
