? operator landed on stable in 1.13 and that my project is still not being used anywhere so breaking compatibility with users on lower versions isn’t an issue, I went ahead and replaced all
try! macros I had with
?. The result is a roughly 20% performance loss: https://github.com/ratel-rust/ratel-core/pull/48#issuecomment-261301646
Nothing in the code has changed aside from the
? change. Are there any side effects of the
? operator that the
try! macro does not have - something that would prevent inlining for example?
