Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

MemoizedValue is a Proc (block) wrapper. It is meant to be used as a configuration value. Subsequent ‘#call` calls return the same memoized result.

Examples:

num = 19
value = Pry::Config::MemoizedValue.new { num += 1 }
value.call # => 20
value.call # => 20
value.call # => 20
