Unusual, granted.  Horrible, why?

I found useful, sometimes, (ab)using Python syntax for representing data
having more or less complex structure.  More than once, it spared me the
trouble of inventing a syntax, and then writing a lexer and a parser.
Letting class constructors returning arbitrary objects has often been
useful in such circumstances.
