I'm seeing this error:

Value 'lib.mecs@131a7516' for variable 'm' has wrong type (lib.mecs)
(lib.mecs cannot be cast to lib.mecs)

Which on the face of things is kind of flabbergasting. The specific
line of code which causes the issue suggests that it is indeed the
case that the value lib.mecs@etc... is a lib.mecs instance and its
being used as a lib.mecs instance.

Any ideas?
