This package contains functionality for validation of a list of values against a specification. Currently, this
specification is accepted in the form of a list of ReflectionParameter criteria, which is
typically retrieved via ReflectionFunctionAbstract#getParameters().
Thus, it is possible to validate a list of arguments to determine whether any function or method can be invoked with
it - without actually invoking.
It is also possible to use functionality in this package to determine whether any individual value matches a type
criterion in the form of a ReflectionType, which is typically retrieved via
ReflectionParameter#getType().
