I did take a brief look at OpenDBX:

Perhaps we'd be better off wrapping this than writing our own wrapper for each

I'd like to wrap C's printf so that I can do something like this:

Which would print "The sum of 1 and 1 is 2."
I realize that I can't use a simple foreign-lambda, as I need to call C's printf

Three that I can think of:
