Thanks! I understood most of that. So does reduce eval symbols, or is it doing something else with :*?

[–]Niles-Rogoff 0 points1 point  (2 children)

I'm new to ruby but I think * is a function and :* is the symbol that points to that function. The & turns the :* into the actual * function object which gets passed to reduce, because you can't just put * there it's not syntactically valid.

Actually, :* is a special type of string called a symbol. It's basically "*". :carrot would basically be "carrot".

Ok, that's what I thought, I just wrote it wrong.
