Seriously tho, that trick can be useful, interpolating constants (which really is calling subs) inside of a string, or more specifically a here doc can be nicer than precalculating and interpolating in.

It can be, but it does come with caveats. Aristotle and I had a short exchange about them once: Re^2: CGI and why?. Basically it boils down to "be wary of context."

I freely admit to using "@{[...]}" fairly regularly myself, though, so I don't mean to discourage it when it makes sense.
