Description

#;1> (string-substitute

 "{12mp}"
 "TRUE"
 "{12mp}"
 #t)

Error: (car) bad argument type: ()

Call history:

<syntax>		(string-substitute "{12mp}" "TRUE" "{12mp}" #t)
<eval>		(string-substitute "{12mp}" "TRUE" "{12mp}" #t)	<--

#;1>

The braces in the regexp are incorrect -- they needed backslashes -- but the resulting error is very unhelpful. The regexp is mal-formed, and the regexp compiler ought to say so.

This is fixed in version 0.8.2 of irregex, which is currently awaiting being integrated into chicken (see `total-irregex` branch of the core system git repository).
