=head1 DESCRIPTION
Let's use L<Benchmark::Featureset::ParamCheck> to see how fast
L<Type::Params> is compared with other modules for validating
named parameters. (Hint: very fast.)
=head1 RESULTS
The results of running the script on a fairly low-powered laptop.
Each parameter checking implementation is called 250,000 times.
The table below displays the average time taken for each call in
nanoseconds.

=head1 ANALYSIS
Type::Params (using Type::Tiny type constraints) is the fastest framework
for checking named parameters for a function, whether or not Type::Tiny::XS
is available.
Params::ValidationCompiler (also using Type::Tiny type constraints) is very
nearly as fast.
Params::ValidationCompiler using other type constraints is also quite fast,
and when Type::Tiny::XS is not available, Moose and Specio constraints run
almost as fast as Type::Tiny constraints.
Data::Validator is acceptably fast.
Params::Check is fairly slow, and MooseX::Params::Validate very slow.
Type::Tiny::XS seems to slow down MooseX::Params::Validate for some strange
reason.
Type::Nano is slow. (But it's not written for speed!)
=head1 DEPENDENCIES
To run this script, you will need:
