◆ cast()

def cast (   self,
  val 
)
Try to cast `val` as a Boolean.

>>> x = BoolSort().cast(True)
>>> x
True
>>> is_expr(x)
True
>>> is_expr(True)
False
>>> x.sort()
Bool

Reimplemented from SortRef.

◆ subsort()

def subsort (   self,
  other 
)
Return `True` if `self` is a subsort of `other`.

>>> IntSort().subsort(RealSort())
True
