The import doesn't necessarily have to be in the same module
where the attribute is used. The first time *any* module
does 'import MMA.grooves', a grooves attribute gets put
into MMA, which can be used by any module that has a
reference to MMA.

It's probably not a good idea to rely on this, though,
and better to put an explicit 'import MMA.grooves' into
every module that uses it. Importing something more than
once does no harm.
