[GiNaC-list] ginsh as a subroutine?

[John Fletcher]

I would like to be able to call a subroutine with a string e.g.

"x+y" 

and receive back an ex object containing the expression and also a 
map mapping "x" and "y" strings to symbol objects.  

The example program ginsh does this internally.  I think it could be 
added within the class for ex objects.  Has anyone done this?

Thanks

John
