Have you really identified String concatenation as the primary issue?
There's so much more going on when building a template (especially in
Rails).

Somehow, my feeling is that the actual concatenation of a small string
takes even less time than the calling overhead of String#<< (accessing
self, method lookup, checking arguments, returning the recipient, ...)
We could be talking about, say, 2% of the time your template needs to
compile.

By the way, fact check: ERb really uses String#<<, right?
