	p	input.r	/^            p <<- fp[-1]$/;"	globalVar	language:R

in expected.tags is questionable. The parser knows p is field of eppFP as printing

	p	input.r	/^        p = NULL,$/;"	field	language:R6Class	class:eppFP

So the parser can emit

	p	input.r	/^            p <<- fp[-1]$/;"	field	language:R	roles:lval
