Re: [Gretl-devel] functions optional arguments - numerical (NA equiv. to null), python like syntax (wish)

But one (somewhat relevant) point is that it's now OK (in recent git) to skip one or more optional arguments altogether, provided one inserts commas to preserve the argument count where necessary. (Commas are not required if only trailing optional arguments are skipped.) For example, if a function foo() takes three arguments, with the last two optional, and a caller wishes to supply only arguments 1 and 3, then foo(x,,z) is an acceptable call. Allin
