Hi,
here's a RFC or a feature request, in some sense:
Currently a gretl 'list' datatype is strictly different from a 'series'
type it seems. So when a user-written function expects a list, you
cannot pass it a series.
(BTW, it the error message was a little strange: something like "unknown
datatype where list was expected", although gretl should recognize its
own series type?)
But isn't a series really a 1-element list? Wouldn't it actually make
sense to not have a different series datatype, just lists with varying
numbers of elements?
Note that the built-in functions for series already seem to honor this
principle, because they accept both series and list datatypes.
I think it's good to think about this before gretl 2.0...
thanks,
sven
