How would the parser disambiguate the import of the module readf from 
the symbol readf in std.stdio?

Just to clarify, does this mean that to import std.c.stdlib as FQN only, 
you would have to do:

import std.c.stdlib as std.c.stdlib; //(1)

Or, indirectly:

import from std.c.stdlib a_symbol_I_will_never_use;

?

1) When you import something as fqn-only, you must be ok with typing out 
the full name quite a lot, so once more will not make much of a 
difference I guess...
