Comment (by vdelecroix):
Replying to [comment:15 mjo]:
> I went with `matrix_space()` because I've never really known what
`parent()` is supposed to do. But I guess it's safe since everywhere else
in the class, "parent" means "immediate parent matrix space." I also
changed the implementation to use a list comprehension (no reason, my
personal taste has changed).
Most objects have a parent. That is the set in which they belong:
{{{
sage: 1.parent()
Integer Ring
sage: Permutation([3,2,1]).parent()
Standard permutations
sage: (1.3).parent()
Real Field with 53 bits of precision
}}}
This is coded at very low level (namely `sage.structure.element`), and
hence very fast. From the parent, you should be able to build new element
of the same set.
