Hmm, interesting. That sounds like a bug, but I'd like one of the
Guile maintainers to clarify that this isn't intended before I look at
it more. Is this triggered when you're trying to load a module full of
infix expressions? If so, how do you tell Guile that the module is
supposed to use infix expressions instead of s-expressions?

Guile versions before 2.0 don't have support for multiple languages.
The big change in the 2.0 release was the move from a direct
interpreter to a virtual machine, which made multi-language support
practical (and also made Guile much faster).
