Calling a mesh instance 'mesh' or 'msh' (to avoid the keyword)

I've been calling my mesh instances `mesh`, but I notice a few other scripts call it `msh`, presumably to avoid the keyword.

Should I adapt to naming things `msh` instead of `mesh`? Would there ever be cases where naming something `mesh` would break your script?

No, I don't think so. After looking in the documentation you should not get any warnings for calling it mesh.
