I had an intern adding that as a bytecode compiler option and make the decompiler compliant with this. One needs to check if everything still works fine but it can be enabled. Something like: <compilerOptions: + inlineRepeat> should already work. I think the idea was to keep limited the number of inlined messages, hence that one is not inlined by default. #timesRepeat: is not inlined either in Pharo. But then where's the limit between what you inline and what you don't... > John Brant >
