[Gretl-devel] foreach-loop over arrays
Hi,
I am not sure the following behavior of bundles and matrices data types
is intended:
While a foreach loop iterates over all items for bundles (items = keys)
and string arrays this is _not_ the case for matrices and bundle arrays
aka bundles. I think it's quite natural that it matrices and bundles
should also be "iterable" but maybe I am overlooking something.
Thanks,
Artur
