There is a new Pharo build available! The status of the build #1 was: FAILURE. Could not extract further issue information from commit message: When compilig {}, we were using a Stream. But that is not needed: we statically know the size of the array, we can just create it and the use a:put: to fill it. - check decompiler: it was not decompiling to {}, but to the generated code. The same works for at:put: - fix #examplePushBigArray, the test is green (it checks execution of code, not the generated code) - remove not needed code int the decompiler,( it was not used before either, as the {} where decompiled to explicit nextPut: sends) - remove #braceArray, #braceArray: and #braceStream: The resulting code is faster, for #defaultColors 1.8 times fixes #14683 Build Url: https://ci.inria.fr/pharo-ci-jenkins2/job/Test%20pending%20pull%20request%20and%20branch%20Pipeline/job/PR-14779/1/
