The way Guile works, being a library, is that there are functions for
interpreting code. So I implemented those functions into some class
objects, so that one can write:
function1<integer, integer> inc("(lambda (x) (+ x 1))");
instead of the
function1<integer, integer> inc = x >>= x + 1;
Now a read-evaluation-print loop just has a line editor which reads
input lines and passes it to some such function, and the prints back
the resulting string. - There is a function display() by which any
object can be made human readable, though not in a way that it can be
converted back to Scheme code.
So perhaps ChucK might be made into some library, though it is great
of not having to fiddle around with C/C++ programming. But having the
option might be useful.
