class Pry::Config::MemoizedValue
MemoizedValue
is a Proc (block) wrapper. It is meant to be used as a configuration value. Subsequent `#call` calls return the same memoized result.
@example
num = 19 value = Pry::Config::MemoizedValue.new { num += 1 } value.call # => 20 value.call # => 20 value.call # => 20
