That's true - there is no support for compiling complex
literals (constants). A work-around is to use (e.g.):
(make-rectangular 3 4)
The correct fix is to make the classes DComplex and CComplex
in gnu.math implement the Compilable interface. It would not
I've been putting it off, because I wanted to figure out a way to not
have gnu.math require gnu.expr. I could hardwire knowledge of the
gnu.math classes into gnu.expr.Literal, but I prefer not to do that.
I think the long-term solution is to use the serialization
framework. The best way to do that I don't know yet.
