as shown by the mod-file in http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=3870, we don’t check whether expressions defined with the pound operator are complex or not. This may lead to cryptic error messages.

What do you think about adding such a check to the preprocessor. In this regard, checking for NaN might also be a good idea.

Actually complex expressions gets translated to NaN (since the preprocessor only knows real numbers). But we want to allow for NaN in some contexts. So it is not obvious how to deal with that.
