strange error

[Martin Baehr]

this one is puzzling:

> mixed fun = lambda(){ return 1; };
> fun[""];
Bad argument 1 to Gmp.mpz(). Expected int|float|Gmp.mpz|Gmp.mpf|Gmp.mpq.
Unknown program: Gmp.mpz(HilfeInput()->__lambda_66024_0_line_1)

canthat be made to print 
Indexing on illegal type.

instead?

greetings, martin.
