Yeah, that's fair enough. (I wrote a parser of my own the other day... 
If you feed it incorrect syntax, it totally crashes!)

Would it be possible to print the NAME of the function as well as the 
expected number of arguments? Doesn't help if you have nested 
invocations of it, but it's a start...
