const Var *	has_var () const
	As above if `this` is a mutable.

Detailed Description

template<bool Up>
class mim::TBound< Up >

Specific Bound depending on Up.

The name Up refers to the property that a Join ascends in the underlying lattice while a Meet descends.

Up = true: Join (aka least Upper bound/supremum/union)
Up = false: Meet (aka greatest lower bound/infimum/intersection)
