    _______________________________________________________

Details:

The $(guile) function does not accept all valid guile code.

For example, the sharps here are unconditionally interpreted as comments:

----make code snip----
libelektros_CFLAGS := $(guile (augmk/pkg-config/cflags "eigen3" #:sedsystem
#t))
----make code snap----

Sharps are fairly important syntactic components of guile --- they are the
syntax both for several literal types and for keyword arguments.  The snippet
illustrates both usages.

Other characters cause problems as well.  For example, adding to the load
path:

----make code snip----
$(guile (append! %load-path (list "./")))
----make code snap----

For this snippet, I get "***missing separator.  Stop.".  I have to explicitly
show make that this is an assignment in order for it to be accepted:

----make code snip----
DUMMY:=$(guile (append! %load-path (list "./")))
----make code snap----

Looking at the parse function, it seems like all function calls are handled as
a variable assignment (possibly to nothing).  However, the manual shows
several non-assignment uses of the $(guile) function, so I assume that this is
meant to be supported behavior.
