That'd be kinda cool.

GOSSAFUNC generates way too much information. If you get to the point where you want to do this, just post the source instead and we can recreate the GOSSAFUNC output if needed.

Perhaps a better button might be go tool compile -S output.

For some time I've been wanting a playground "secret menu"—maybe query params?—for things like compiler flags -S, -m, -m -m, -n, -l. This fits in naturally with that. I'd want the HTML, not the terminal output. Anyway: yes please!

Konami Code.

I was more thinking In'n'Out.

Should it be "totally" secret (no cue in interface)? In that case I propose that we add some parameter "debug" or "gcflags" that can be passed in the url. There you could specify some allowed set of compiler flags (go build -gcflags). Let's say we start with -S, -m, -l. Also do not allow anything other than combination of those flags and spaces.

Should we include the secret switches into the calculated hash code for sharing the program? I think yes, we could do that to allow sharing it.

The output from the compiler could be displayed prior the output from the program. Ending with this magic phrase "Go build exited." I am not sure how it can be converted to HTML. I thought about just dumping out the textual output.
