Comment (by rhaas):

 I was not really serious about adding system(). I find it rather horrible
 to tell the truth :-). For this kind of thing I would think using
 parameter scripts (eg. perl is very well suited to these unstructuted
 things, being a unstructured language itself :-) ) is best. Unless you
 really need access to things that only exist during runtime. I currently
 only supports numbers in the expression parser, eg something like `whoami`
 or `hostname` does not work.
