args :: Args

Default arguments to Speculate

foreground :: Expr

A special Expr value. When provided on the constants list, makes all the following constants foreground constants.

background :: Expr

A special Expr value. When provided on the constants list, makes all the following constants background constants. Background constants can appear in laws about other constants, but not by themselves.
