| Subject: | Future::AsyncAwait with "perl -w" emits warnings |
I sometimes check perl scripts by running "perl -wc script.pl".
Currently scripts that use Future::AsyncAwait emit warnings:
```
❯ perl -MFuture::AsyncAwait -wc -e1
Name "XS::Parse::Sublike::ABIVERSION" used only once: possible typo at /Users/skaji/env/plenv/versions/5.30.2/lib/perl5/5.30.2/XSLoader.pm line 114.
Name "XS::Parse::Sublike::PARSEANY" used only once: possible typo at /Users/skaji/env/plenv/versions/5.30.2/lib/perl5/5.30.2/XSLoader.pm line 114.
Name "XS::Parse::Sublike::REGISTER" used only once: possible typo at /Users/skaji/env/plenv/versions/5.30.2/lib/perl5/5.30.2/XSLoader.pm line 114.
Name "XS::Parse::Sublike::PARSE" used only once: possible typo at /Users/skaji/env/plenv/versions/5.30.2/lib/perl5/5.30.2/XSLoader.pm line 114.
-e syntax OK
```
It it nice Future::AsyncAwait suppresses these warnings.
I'm using Future::AsyncAwait 0.40 and perl 5.30.2.
