I am sorry to have been unclear. Let me try to
make this point clear with a literal example.
The following program:
--------------------------------
template<typename TYPE>
int foo(TYPE const& i)
{
char* c = i;
}
int main(void)
{
int* i;
foo(i);
return 0;
}
--------------------------------
Gives WITH my patch the unambigious error:
tp.cc: In function `int foo (TYPE const&) [with TYPE = int*]':
tp.cc:10: instantiated from here
tp.cc:4: cannot convert `int* const' to `char*' in initialization
While WITHOUT the patch, it says:
tp.cc: In function `int foo (const TYPE &) [with TYPE = int *]':
tp.cc:10: instantiated from here
tp.cc:4: cannot convert `int *const' to `char *' in initialization
I'll restrict myself to saying that I _personally_ find
the first error much better readable and certainly not giving
any room for an ambigious meaning of what the type of the
parameter of foo() might be.
Anyway, I hope this example clearifies what I wanted to
point out.
