Async Transformers

I was using Compiler API and basically changed program.emit at host.afterProgramCreate just like examples and hooked my transformers into emit function. But one thing i couldn't find anywhere is a async transformer. Im using PostCSS and some other stuff like that and implementing those to a single typescript compiler but some plugins are async in postcss and i cant use them at the moment. Is there any way to implement this that im missing or undocumented ? And in case somebody offers to use webpack my code is mostly javascript based and i need really good static analysis for it with type data included that's also reason i use typescript's api instead of using babel which have those cases mostly covered with plugins. I'm implementing all-in-one solution for my company/community project so ideally it needs to be inside typescript compiler.

Inizia dai punti di ingresso di Compiler API indicati nell’issue: program.emit e host.afterProgramCreate, quindi confronta il ciclo di vita dei transformer con quello dei plugin PostCSS asincroni coinvolti. Il lavoro è completo quando viene stabilito se i transformer asincroni sono supportati oppure viene documentata una modifica concreta e circoscritta del compilatore necessaria per supportarli.
