Replying to [comment:3 timdumol]:
> Functions that inherit from `PrimitiveFunction` are automatically given
`nargs = 1` on L800 of `symbolic/function.pyx`. So the silent dropping of
arguments is more of a usability problem on the Symbolic side.
You're right. I fixed this and many other things about symbolic functions
last weekend, by rewriting sage/symbolic/function.pyx. Unfortunately I
don't think I'll be able to clean up my changes and submit them any time
soon... oh, well...
I'm giving your patch a positive review. It applies cleanly, and passes
all tests on my 4.1.1.alpha. Great job! Many thanks.
