[Scilab-users] Mysteries in the Realm of Overloading Catenation Operators (",", "; ") in Scilab 6.0

[Dirk Reusch]

Hello,

Using precompiled Scilab 6.0.0 Linux 64bit, exploring the announced
"ability to define user types in C++ modules" (cf. Scilab 6.0 - Release
Notes February 15th 2017) ... reveals the following:

Startup execution:
  loading initial environment

-->
exec('/home/dirk/Downloads/scilab-branch-6.0-1488991653/modules/ast/tests/unit_tests/newtype.tst',-1)

This is my type.

 %nt_p: This is my type.

--> [a;a]

Undefined operation for the given operands.
check or define function %nt_f_nt for overloading.

--> [a,a]

Undefined operation for the given operands.
check or define function %nt_c_nt for overloading.

--> // So far, it's Ok!, but trying to ..

--> [a,1]

inconsistent row/column dimensions

--> [a;1]

inconsistent row/column dimensions

--> // .. is IMHO not OK!

--> // Why does Scilab here *not* try to call "%nt_c_s", or "%nt_f_s" ?

So it seems IMHO, that the "ability to define user types in C++ modules"
is currently in a rather broken/incomplete state ... but, I am looking
forward to see things improving.

Thanks for any advice and further insight,

Dirk

PS: Tested also with nightly build  branch-6.0-1488991653 ... with the
very same mysteries!
