    return Just(match=x)

def isNothing(x):
    return x==Nothing

type-classes

def mapB(func, b):
    return b


T, F = newType("B", ("T",0), ("F",0), deriving={Eq, Show}, implements={Functor : {"fmap" : mapB} })

print(fmap(lambda x: x*2, T)) # 'T()'

operators

# Application operator $ as |

@pylu
def f(x):
    return x

print( f | (lambda x: x*3) | (lambda x: x+1) | 2) #9


# Function composition . as *

g = (lambda x: x*3) * f * (lambda x: x+1) * (lambda x: x+1)

print(g(2)) #8
