end

#set(name, val = nil, &b) ⇒ Object

Declare a variable called name and assign it a value. A globally-visible method with the name of the variable is defined. If a block is given, it will be called when the variable is first accessed. Subsequent references to the variable will always return the same value. Raises ArgumentError if the name would conflict with an existing method.

def set name, val = nil, &b
