Nested parentheses in imports/exports are not parsed correctly

So it seems to me there are at least two problems here.

1. at least in export lists numbers are not considered part of a functions name
2. Export lists are prematurely terminated in the presence of a closing paren. This does not change with the addition or removal of a newline.

The weird colouring for the numbers is due to the parenthesis bug, it works fine otherwise:

Without nesting parentheses, it works fine:

Same here:

Good code, bad parse:
