Yes! After we finish the front end I want to do a pass again on the backendâ¦ there are still some things to simplify, and these look interesting. Opal TODO right now: - refactoring to the new API - AST Transformer Plugins - compiler Pragmas (to turn of inlining, for example.) - get non-boolean receivers for ifTrue: working even when optimizing (see mustBeBooleanIn:) - Pluggable everything (so people can exchange everything (Parser, Semantic Check, Translator, IR backendâ¦) - Write something about it so people can use it - Do another pass on the backend Marcus

So when you commit MC tries to be smart and gather a unique version number by checking ALL repositories ... there is your issue :(

Same problem in same train situation. I press commit on local directory and system start connect to smalltalkhub repository and hang for ever.
