If you need to edit the code, you might as well use an editor anyway,
and if you use a Real Editor (:-P) like vim or emacs you *could* just
bind a single keystroke to invoking `dmd -run`.

Or better yet, use the new `dmd -` to compile the code directly from the
editor buffer via stdin, with `-of` set to some generic filename (I like
to use /tmp/text or /tmp/x, for example), then your keybinding could be
something like `| dmd - -of /tmp/test && ./test`.  Then you could
literally execute the editor buffer with one keystroke.  And this works
even when you're offline.

Sadly, `dmd - -run` currently doesn't quite work just yet. I should look
into fixing that.  And *then* we wouldn't need to invent a temporary
filename for the executable in our keybinding.

(Of course, none of this negates the value of run.dlang.io -- I'm not
arguing against that. It's just that testing out quick snippets seems to
be a flimsy excuse to need to use it. :-P)


Heads I win, tails you lose.
