I thought this article was very interesting. Thanks for posting it!
One thing that I thought was very interesting was their way of allowing
for custom inline operators in python. It inspired the following
@inline_operator decorator. Would this be useful in Sage?
class inline_operator:
def __init__(self, function):
self.function = function
self.left = None
self.right = None
def __rmul__(self, left):
if self.right is None:
self.left = left
return self
else:
right = self.right
self.right = None
return self.function(left, right)
def __mul__(self, right):
if self.left is None:
self.right = right
return self
else:
left = self.left
self.left = None
return self.function(left, right)
# EXAMPLE
a=[1,2,3]
b=[3,4,5]
# This emul operator returns the element-wise product of two lists...
@inline_operator
def emul(a,b):
return [i*j for i,j in zip(a,b)]
# Returns [3,8,15]
a *emul* b
Thanks,
Jason
