Thank you woei! Reminds me I did something similar together with @antongit. This ended up in a branch that should be merged back these days. 1c6b3e9e4739e4374b2e9c0dd918d0d5399c7056 Will have a look then

[woeishi]

That looks about the same minus the bounds checks

and note L948 looks like a copy paste error in context with L905 since both condition check for the same type
