Consider the following makefile:

ALPHA = foo
BETA  = $(ALPHA) bar

all:
	echo $(BETA)

Running make with this makefile will result in the execution of the
command "echo foo bar", which is OK.

Now, consider the following makefile:

ALPHA = foo
BETA  = $(ALPHA) bar

all:
	echo $(BETA:bar=hello)

Running make with this makefile will result in the execution of the
command "echo $(ALPHA) hello", which is certainly not what I would
expect.

Why is ALPHA not substituted in the last example? Bug or feature?
