The only benefit would be the string formatting; the expressions have
to be evaluated still. Is that worth it?

Of dubious value, since the strings have to be externalized. MAYBE
useful but would need something complicated where the original form is
a code construct, but the i18n library can get the source code and use
it as a lookup key to find the translated form. Seems pretty messy.

You shouldn't be sanitizing your expressions, you should be
parameterizing your query. That doesn't mean this is of *no* value,
but it does make it look a lot less like a string literal.

Of value only if it gets an extremely compact syntax. Other use-cases
could be better served by a syntax like html(i".....") but this one
only works if it's that kind of notation.

Not sure how this would work, but given that I don't use Lisp enough
to be familiar with the use-cases, I won't argue this one.

Explain?
I'd love to have some sort of generic interpolation construct, but the
use-cases all seem really weak...
