That's simply not a good idea, instead add both table entries

    .foo.example some action
    foo.example some action

This is simple and clear enough and no further syntax is needed.
If that's somehow too burdensome, "make" is your friend:

	$ (
	    ls -l foo* Makefile
	    make foo
	    for file in foo foo.map Makefile
	    do
	        printf "\n=== Content of %s\n" "$file"
		cat "$file"
	    done
	  )
	-rw-r--r-- 1 viktor viktor 124 Aug 21 11:51 Makefile
	-rw-r--r-- 1 viktor viktor 154 Aug 21 11:38 foo.map

	+++ Constructing foo

	=== Content of Makefile
	.SUFFIXES: .map

	.map:
		@printf '\n+++ Constructing %s\n' "$@"
		@perl -lpe 'print $$1 if (s{^[+]([a-z\d].*)}{.\1})' $< > $@

	=== Content of foo.map
	domain-only.example REJECT 1
	explicit-with-subdomain.example REJECT 2
	.explicit-with-subdomain.example REJECT 3
	+implicit-with-subdomain.example REJECT 4

	=== Content of foo
	domain-only.example REJECT 1
	explicit-with-subdomain.example REJECT 2
	.explicit-with-subdomain.example REJECT 3
	implicit-with-subdomain.example REJECT 4
	.implicit-with-subdomain.example REJECT 4
