No function pointer.  However, there are other alternatives.

The functions merge() & value() and commands 'do', 'call' & 'send' all 
evaluate and might be useful.  There are ways to execute commands in 
the first and functions in latter.  Besides using function names, you 
can also create expressions and evaluate those in the appropriate 
context.

You can return values from a 'send' (not in time) by using return in 
the callee and looking at result() in the caller.
