DOLFIN does this:

form_compiler = __import__(form_compiler_name)

where form_compiler_name can be "sfc". Since DOLFIN does not set this
name to be "sfc", I think it should be ok.

On the other hand, I doubt this would be ok:

form_compiler_name = "sfc"
form_compiler = __import__(form_compiler_name)

I think so, if somewhere in sfc you have "import syfi".
