I am no friend of the preprocessor.
But this at least is no new problem: C has exactly the same
problem, and presumably the C and C++ support in Eclipse
already does something with it. (If the editor manual is
bigger than the listing of my editor, I don't use it. Eclipse
massively fails this test, so I don't know much about it.)
I presume it goes something like this:
if it looks like a variable, display it as one;
if it looks like a function call, display it as one;
if the display is wrong, it's the programmer's fault
for defining such a stupid macro.
There's one possible extra you _might_ want to consider.
I have C macros that would benefit from it.
%%erlide%% begin_like <macro name>
%%erlide%% end_like <macro name>
so that for example you could use
%%erlide%% begin_like SPAWN
%%erlide%% end_like END
-define(SPAWN, spawn(fun () ->).
Pid = SPAWN
and have it coloured/styled/indented appropriately.
