Thanks for pointing that out. I was actually surprised to see my test work,
since I knew boolin expected cstring. I forgot that by not providing a type
strings get treated specially.

I don't remember ever running accross documentation on how to solve this
problem. Even something noting that most of the type input and output
functions are named typein and typeout and that to convert to text you can
use textin(typeout(typevalue)) and to convert from text you can use
typein(textout(text)) would probably be good enough.
