The parser is a bit old and creaky in the joints, and some of its
features may interfere in unexpected ways.

For instance, while parsing the parameter list of a macro invocation,
the parser doesn't like directives (`#if`, `#else`, `#break`, ...) after
a `texture{}` statement -- presumably as an unintended side effect of
the layered textures feature (`texture{} texture{}`).

A simple workaround is to first assign the result of the texture macro
to a temp variable, and then use that temp variable in the object macro
invocation.
