Constant Declarations

Constant values must be able to be determined at compile time to be valid.

You can use identifiers in constant declarations, but they must resolve as constant expressions, as well.

Declaring Constants

Users can map constant identifiers to any constant value:

  const Real pi = 3.14;;

  const yellow of color = 
    red   = 255,
    green = 255,
    blue  =   0;;
