#6977: [with patch, needs work] Implement __len__ to add support for MuPAD
objects
as Python containers
-------------------------+--------------------------------------------------
Reporter: nthiery | Owner: nthiery
Type: enhancement | Status: assigned

Component: interfaces | Keywords: MuPAD len
Reviewer: Mike Hansen | Author: Nicolas M. Thiéry

-------------------------+--------------------------------------------------
Comment(by mvngu):
Any doctest involving MuPAD must be tagged as optional, otherwise one
would get doctest failures. For example, for the patch
`trac_6977_mupad_len.patch` the test
{{{
sage: len(mupad([1,2,3])) # indirect doctest
}}}
depends on having MuPAD one's local machine, so it should be written as
{{{
sage: len(mupad([1,2,3])) # optional indirect doctest
}}}
After applying the patch, I got these doctest failures:

In order to use the MuPAD interface you need to have MuPAD installed
and have a script in your PATH called "mupkern" that runs the
command-line version of MuPAD.
