I spent over an hour to locate a bug in my SDL code... There is none! But I
found that adding a semicolon after declaring my texture fixes the problem..
How comes this?  Maybe I'm just not aware of this new development - that
semicolons after texture declarations keeps the parser from being confused..
Is this behaviour intentional?  Here's an example:

#macro Define_Plastic( Pigment_1 )

 #local Plastic=texture { pigment { rgb 1 }
  }; // SEMICOLON FIXES THE PROBLEM

 Plastic
#end

#local White_Plastic=Define_Plastic( 1 )


Regards,

Probably. Just check how layered texture can be created.

That semicolons can now be used to disambiguate layered texture declarations
from other textures that just happen to be adjacent is something that just
came for free with the change that allows semicolons after any #declares.
So was it intentional?  Sorta.
