Params::ValidationCompiler creates a customized, highly efficient parameter
 checking subroutine. It can handle named or positional parameters, and can
 return the parameters as key/value pairs or a list of values.
 .
 In addition to type checks, it also supports parameter defaults, optional
 parameters, and extra "slurpy" parameters.
 .
 A parameter specification can be provided as either an arrayref (which expects
 positional params) or a hashref (which expects named params). Parameter types
 can be specified as Moose, Type::Tiny or Specio type objects. Parameters can
 be specified as being optional and can be provided with default values.
