| This also works for things like
|
| foo = mumble
| foo = blurgle
|
| which would be interpreted as
|
| foo = blurgle
| if FALSE
| foo = mumble
| endif
I've always thought this is wrong. I still think we should not
support such ``feature'', which is a form of laxism to me, comparable
to globbing.
Nevertheless, I agree a means to install defaults would be most
welcome.
I suggest introducing
foo ?= bar
Which is always valid, but with a clear semantics.
Also, maybe we want to introduce something like (hold you breath):
ifndef foo
foo = bar
endif
