[Gretl-devel] reserved words issue

Not so long ago I tightened up on potential trampling of reserved words in hansl, one effect being that you can no longer define a variable with the same name as a built-in function. I now notice that this provokes an error in the gig printout function, which defines a scalar named "nobs". At first I thought this must be an error in the reserved-words apparatus (isn't it just "$nobs", with a dollar, that's reserved?). But on closer inspection I see we also have a function nobs(), which gives the number of non-missing observations for its series argument in the current sample range. Not a terribly useful function, but it's used in a few packages. So I've (locally) committed a little change in gig, "nobs" -> "T". This is basically just a heads-up that I/we need to check all packages carefully for such collisions before the next release. If necessary, I guess we could create an exception or two on a temporary basis (that is, for now permit masking of a few little-used function identifiers). Allin
