Something that would improve a lot the PARI interface would be someone
would implement a toy GP-like program (that would read input line and display
the result, deal with error correctly, etc.) that would follow the 
_documented_ PARI interface. This would be distributed as an example of PARI
program. This way interface problems would stand out.
