Extended Description

One would like to use the following overloading of functions in the 
stdlib's FibreIO module:
double[*]  FibreScanDoubleArray( File &stream);
double[*]  FibreScanDoubleArray( TermFile &stream);
double[*]  FibreScanDoubleArray( string stream);
double[*]  FibreScanDoubleArray()
However, we get:
> ABORT: line 72  file: FibreIO.sac
> ABORT: Trying to overload function "FibreIO::FibreScanDoubleArray" that
> ABORT: expects 1 argument(s) and 1 return value(s) with a version that has
> ABORT: a signature differing in the number or position of reference args
> ABORT: only.
The instances do differ in the number of reference parameters, indeed, and I do
recall that there are some limitations in the implementation. Apart from
the fact that this is rather unfortunate, I don't think the error message
is spot on: There's also the string argument in the 3rd instance that the others lack.
I think it should be possible to distinguish the cases even at an early stage in the compilation.
