Hi.

FWIW. With my current yuqk fork(a) running what Bill posted, without the 
second declaration of a M_Granite texture ID or the added semicolon, I get:

File 'granite_texture_1.mcr' line 580:
Parse Error:
Cannot assign uninitialized identifier 'M_Granite'
to non-optional LValue of:
'Tex'.
This error sometimes comes about due a prior, situationally, missing 
semicolon.
Fatal error in parser: Cannot parse input.
Render failed

There are issues in all the recent parser variations with respect to 
sometimes necessary, but missing semicolons. The yuqk fork has addressed 
a few of them in its version of the parser, but certainly not all.

The worst cause flaky behavior during parsing without any notice 
something has gone wrong.

(a) - A version compiled to allow lower case identifiers. Plus, I needed 
to add the noise generator to use as the last argument to f_noise3d(). 
The inbuilt functions in official releases of POV-Ray always use noise 
generator 2.
