--- Comment #6 from Manu <turkeyman@gmail.com> ---
Okay, so this has obviously come up a lot.
It's a real problem not being able to express any non-linear function in CTFE.

I'm changing this to a high-priority bug, rather than an enhancement request. I
don't think pow() was deliberately designed not to support CTFE(?).

It's an operator (^^), and users should surely expect that all basic operators
work in CTFE.

I'm changing this to blocker.
Seriously, it's gone on long enough. 5 years apparently according to this bug
report.

It is actually blocking a whole bunch of projects. They are literally sitting waiting for this bugfix. We can't generate compile-time data/tables without this super-important function. There's no substitute or workaround. We need to be able to evaluate non-linear functions in CTFE.

log() works! pow() is the rather more frequently occurring compliment.

> log() works!

I doubt that, CTFE isn't powerful enough yet.

Disbelieve it all you want, it does work.
