Description:
facility for creating read-only scalars, arrays, and hashes
Const::Fast is a perl module for creating read-only scalars, arrays, and hashes. It enables you to set a variable to the given value and subsequently make it readonly. Arrays and hashes will be made deeply readonly. . This module uses the builtin readonly feature of perl, making access to the variables just as fast as any normal variable without the weird side-effects of ties.
