What about Argument-Dependent Lookup (C++ has it)?

The file1 package was "withed", which makes the type accessible. If the 
compiler is smart enough to figure out the expected type of literal, 
then it should be also smart enough to look up any operators (and why 
not other operations as well?) that are used together with the literal 
in the package from which the expected type come from. That would 
provide the "expected" functionality.

I'm really surprised that the code posted at the beginning of this 
thread does not compile. I'm pretty sure that something like ADL was 
considered for Ada, but apparently rejected. What was the reason?
