I was wondering if it was possible to call D functions by
their names (strings that are not known at compile time) and
couldn't find the answer anywhere in the documentation. Kinda
like we can instantiate objects with Object.factory, would it
be possible to somehow do the same with module-level
functions? Or maybe with non-static class methods?
You could make an associative array of function pointers with
strings as keys. Probably not the best solution but it should
work.
Thanks for the reply, this is something I thought about of
course. But what if I have hundreds of functions to dispatch to?
The current (C) implementation does exactly that, autogenerates a
sort of an associative array, but that's very ugly and requires
an extra preprocessing step.
I was thinking runtime reflections can help do this, but I'm not
quite sure where to start (and there is also the performance
question).
