$"string" competes with /bin/gettext. Whatever you do, it will be hard
to be slower than /bin/gettext :)
I really would opt for *flexibility* and implement the spirit of the
POSIX shell standard first. We can look at performance later, if there
is the need to do so. But I doubt it will be a problem for the time
being.

3rd possibility is to add a compile time switch that distributions can
pick either flexibility or speed for $"string" literals. But I doubt
speed is a problem, compared to the other issues I explained earlier.
