Re: struct accessors are not inlined even with declaimations

Hey,

thanks for the report!

coincidentally I've stumbled upon that recently:
https://turtleware.eu/posts/A-brief-note-about-slot-access-cost-in-Common-L=
isp.html
scroll to struct access remarks.

I want to address it after other pressing issues are resolved
(I'm working on accessor dispatch performance and slot-value now).

Best regards,
Daniel
