###### Symbol#to_proc

# Putting & in front of a symbol calls the symbol's to_proc method (Symbol#to_proc) and then converts the proc into a block.
#
# &:foomethod converts :foomethod into a block that takes the first yieldparam as the receiver and any later yieldparams as
# argumentds and calls :foomethod
