Ha! That's very cute indeed Philip. Nicely done.
For Andre: the reason this doesn't work is the same reason that an
"include" containing a target setup cannot be followed by the recipe for
that target after the include; this won't work:
include target.mk
@echo this is the recipe
For both include and $(eval ...) the makefile that is included or eval'd
is always parsed by make as if it were a self-contained makefile, and
the end-of-file (or end-of-string) markers will be interpreted by make
as ending any target that is currently being parsed.
