Constructor Detail

def self.new(block : -> T, label : Label = nil) #

Creates the block expression from a proc. The proc will be called to evaluate the value of the expression. The label is usually the Crystal code for the proc. It can be nil if it isn't available.

def self.new(label : Label = nil, &block : -> T) #
