[Gretl-devel] null list as parameter

I had already mentioned this bug, but I can't find where. Anyway, it is still here. With a function declaration like this: function foo ( series a, scalar b[0::1], scalar c[0:2:1], const list d[null], scalar e[0:2:0]) I'm supposed to be able to invoke the function just with a simple: foo(a) where a is a a series obviously. Instead, gretl wants at least: foo(a,b,c,d) because does not accept the absence of the list, whereas it should be allowed by the [null] tag. Cheers. Stefano
