foreach + define + variables ?

[Aleksey Yakovlev]

Hello,

I'm trying to understand how "foreach" interacts with "define". The fragment below prints "1 2". I expected "1 2 3".... Why is the last letter missed?


define F
  var := $(1)
  debug += $(var)
endef

$(foreach p,1 2 3,$(eval $(call F,$p)))

all:
    @echo $(debug)


Thanks
Alex
