hope someone can explain what it means, or confirm that it is an

please help document it here:

Thanks!

Neither auto nor final is valid on a function parameter, so either the
grammar is wrong, or InOutX is not used for function parameters. But looking
at that page, I'd have to spend a fair bit of time working through it to
figure out what it's actually saying.

The bug for tracking all known grammar issues is here:

https://issues.dlang.org/show_bug.cgi?id=10233

And Brian Schott (who's trying to get all of the grammar issues fixed) has
his own version here

Start from "Parameters:" and instantiate subitems until you reach 
InOutX :-)
InOutX is definitely (and only) used for function parameters.

Great, thanks!

Thanks for the link. It is also wrong in his grammar: 
parameterAttribute contains both "final" and "auto".
