I don't quite understand the part with void returns and overloaded
and non-overloaded functions. Obviously, overloaded function
declarations can't differ by return type only. Do you suggest
to supply a non-throwing function with a different name/scope
or a function template?
If so, how should its interface look like?

FWIW, I've often used a scheme of:

void foo() { check(try_foo() ); }
error_code_t try_foo() { ... }
int bar() { int ret; check(try_bar(ret)); return ret; }
error_code_t try_bar( int& i ) { ... }
