[Pharo-project] Feature request for Opal

I want an API for easy plugging in an arbitrary pragma handler, which could then either completely intercept parser/compiler output or modify output. This is userful for things like clean implementation of FFI pragmas, without patching the Parser as well as for scenarios like: myMethod: myArg <myLanguage> foo|<bar**baz so, once pragma <myLanguage> parsed, and handled, an input source stream redirected to completely different parser/compier pair which, of course, should produce a compiled method as a result, but may use any syntax. -- Best regards, Igor Stasenko AKA sig.
