Each exp2 overload forwards to template exp2Impl, and each are marked pragma(inline, true). So this should work if the inlining is done. (Though currently it makes no difference using -inline -O or not).

Unfortunately, run.dlang.io's run-all D compiler option appears to be broken, so I can't test if the recent changes to dmd's inliner caused this to break and hence be a regression.

But yeah I see three possibilities here:

1) Fix inlining
2) Template exp functions
3) Use libc pow instead

Of course, all these options are ignoring the forest. Why are there compiler hooks implemented in Phobos?

Any `T ^^ float` operation is by definition non-trivial, so I'm tempted to just close this as wontfix.
