Method doesn't decay

[seven1240]

pure function args can be decayed to C, e.g.

package freeswitch

//so:extern
func Infof(format string, args ...any);

...

freeswitch.Infof("%s", "hello")

But method (functions with a receiver) doesn't decay.

//so:extern
func (session *Session) Infof(format string, args ...any)

the above code will generate:

    freeswitch_Session_Infof(session, so_str("in app\n"), (so_Slice){(void*[0]){}, 0, 0});
    freeswitch_Session_Infof(session, so_str("%s"), (so_Slice){(void*[1]){&(so_String){so_str("in app\n")}}, 1, 1});

That's by design. Methods do not support decay because they are not meant to be extern.

I can see that in your example Session.Infof is made extern because it's a C variadic:

#define freeswitch_Session_Infof(s, ...) switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(s), SWITCH_LOG_INFO, __VA_ARGS__)

This is an interesting use case, and I hadn't considered it. I'm not sure it justifies adding decay support to the methods, though.

Maybe it's fine to support it given extern methods already working. And it's a nice syntax sugar anyway. Or add a so:extern decay explicitly to force decay even not by default.
