Strange error from %search-load-path via include-from-path when parameter is not a literal string

[Ian Hulin]

Hi,

I'm trying to write a V2/V1 compatible function like the following:

(define (ly:include the-file)
  (if (string>? (version) "1.9.10")
      (include-from-path the-file)
      (load-from-path the-file)))

I get
ERROR in procedure %search-load-path: Wrong type to apply in position
1 (expecting string): the-file.

Bug or user error?

(include-from-path) also gives similar errors at the REPL when the
filename argument is not a literal string.

Guile Version is 2.0.2

Cheers,
Ian Hulin
