Hello all, News: on Monday I will merge into git master my up-till-now "experimental" branch that allows arbitrary nesting of the "member-of" relation in the context of function calls and assignment. (Thanks to Sven for pointing out the previous lack of this feature.) There follows a small sample of the sort of thing that now works: <hansl> # matrix in array of matrices in array of bundles bundles B = array(2) matrices B[1].M = defarray(I(3), mnormal(2,2)) B[1].M[1][2:3,2:3] += 17 eval B[1].M[1] eval B[1].M[1][2,2] # assign to bundle members directly bundle b scalar b.num = 3 matrix b.mat = I(2) # assign to array member with type spec matrices M = array(2) matrix M[1] = I(3) # OK M[2] = I(4) # implicit type, OK string M[2] = "foo" # error, wrong type for array </hansl> After the merge I will consider it a bug if a well-formed instance of this sort of nesting doesn't work. (Up till now I've claimed it's just an "unimplemented feature"). Warning: I have tested this quite thoroughly but there's no guarantee that I haven't missed some problem, so anyone in the habit of using gretl-git for "real" econometric work should be cautious at first. I've checked that the following work OK: all the "practice" scripts packaged with gretl, all of my large and miscellaneous collection of scripts gathered from various sources over the years, all current function packages, and all current addons. I've also put the new code through its paces under valgrind and have fixed all bad accesses and memory leaks that I found in earlier drafts. There may nonetheless be some problems that have not manifested themselves so far. Invitation: I'll be glad if some people are willing to test the new code -- that's the only way we'll be able beat out remaining bugs. For those on Windows or Mac who regularly use snapshots but don't build from git: I'm thinking about creating snapshots from the new code but (for a while) putting them in a new "testing" directory on sourceforge rather than the regular "snapshots" directory. Please let me know if this is something you might use. Allin
