Functions are defined with ∇, and comments start with ⍝ ? I am liking the fancy symbols 
Follow
@vaporeon_ in physics we use the ∇ symbol all the time in electricity & magnetism 
@wallhackio But I'm sure you don't use the ⍝ symbol!
@vaporeon_ we don't unfortunately! but ∇ is used as a notational shorthand for all sorts of operations in vector calculus :D
@wallhackio Isn't it used in mathematics, too? But I completely forgot what it does... Do you remember?
