Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: TestML, TestML::Bridge, TestML::Compiler, TestML::Compiler::Lite, TestML::Compiler::Pegex, TestML::Compiler::Pegex::AST, TestML::Compiler::Pegex::Grammar, TestML::Library, TestML::Library::Debug, TestML::Library::Standard, TestML::Runtime, TestML::Runtime::TAP, TestML::Setup

Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.
