Hi!
In 2.1.8/2.2.0, walking up the stack to find the origin of an unbound
variable error yields inaccurate location info. Consider this:
--8<---------------cut here---------------start------------->8---
(list 'a
(symbol->string 'b)
(symbol->string 'c) ;← unbound variable error reported here
(FOO 'bar) ;… instead of here
3
4)
--8<---------------cut here---------------end--------------->8---
We get:
--8<---------------cut here---------------start------------->8---
$ guild compile -t value t.scm

It Would Be Nice if we could get the right location info here, though I
understand this is a corner case.
Thoughts?
