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.
