Be careful with dynamic-require; it uses (current-namespace), which is
not necessarily the same namespace that the enclosing module was loaded
in. Specifically, you might get a different module registry, which can
lead to multiple module instantiations, which can lead to problems with
generative structs, etc.
Also, with plain dynamic-require, if you build an executable ("raco
exe") it probably won't include the dynamically-required module.
I recommend using lazy-require (from unstable/lazy-require) instead. It
handles both the namespace issue and the "raco exe" issue automatically.
That is teh awesomes, so I've changed it. I had a couple other uses of
dynamic-require, so I changed them to top-level lazy-requires as well.
Any plans to support other kinds of objects than functions?
