Re: [Gretl-devel] freeze .... null default for matrices in packages editor
Anyone have reason why we should wait?
Dear Allin,
The package editor seems to not know yet
about new feature of matrices as a function
argument
When I try to package something like that
function void ma (scalar x , matrix m[null])
isnm = isnull(m)
if isnm
print "null matrix"
else
print m
endif
end function
After saving the ma.gfn
The function becomes
function void ma (scalar x , matrix m)
i. e. "[null]" is autodeleted

I can see why you're sighing. But anyway, thanks for bringing this
bug to light; I think it must have been lurking for quite a while.
it was to do with a subtle type-mixup between the two expressions
joined by "||" (OR). (I mean an internal mixup, nothing wrong with
your hansl code.) It's now fixed in git and snapshots.
BTW, I think we have by now accumulated more than enough bug-fixes
to justify a new release. Anyone have reason why we should wait?
Allin
