[OpenSCAD] Curious lack of error message

[David Goodenough]

I made a typo, and openscad reported only that there were no 
top level objects to work with.  The type was:-

use <file.scad);

In other workds I used a ) not a >.  I presume that the parser
simply ran to the end of the file looking for a > and did not find one.

I would have expected a syntax error in that the use statement 
effectively never finishes.
