To put this another way (forgive any errors in my syntax, I'm not used 
to it):

ImportDeclaration:
	import ModuleNameList ;

ModuleNameList:
	ModuleNameAliasWith
	ModuleNameAlias , ModuleNameList

ModuleNameAliasWith
	ModuleNameAlias
	ModuleNameAlias with IdentifierAliasList

ModuleNameAlias:
	ModuleName
	ModuleName alias Identifier

IdentifierAliasList:
	IdentifierAlias
	IdentifierAlias , IdentifierAliasList

IdentifierAlias:
	Identifier
	Identifier alias Identifier

Note that this means that as soon as "with" is used, you cannot specify 
any more modules in that import statement:

// Imports modules foo, bar, and baz, and aliases
// baz.a, baz.b, and baz.c
import foo, bar, baz with a, b, c;
