GHOST converts pronoun I and names to lower case when passes them to a method.

[stellarspot]

Run the code:

(use-modules
 (opencog)
 (opencog nlp)
 (opencog nlp relex2logic)
 (opencog ghost)
 (opencog ghost procedures)
 (opencog exec))

(define-public (where-somebody-work who-list)
 (display (string-append "argument: " (cog-name (car (cog-outgoing-set who-list))) "\n"))
 (Word "SomeCompany"))

;; Ghost Rules
(ghost-parse "
r: (where do _* work) '_0 work in ^where-somebody-work('_0) company.
r: (where does _* works) '_0 work in ^where-somebody-work('_0) company.
")

; Test Ghost
(test-ghost "Where do I work?")
(test-ghost "Where does Alice works?")

"I" and "Alice" are passed as "i" and "alice to the where-somebody-work method.
Using single quote '_0 for the local variable value does not help as well.
