How can I measure the performance of my q code?

Basics

What exactly does column oriented mean?

–

Does q pass-by-value or pass-by-reference?

–

Is the q language simply syntactic sugar on top of k?

–

What does it mean for q function or table to be a ‘first class’ type?

–

How do I comment q code?

–

I understand whitespace matters in q code. Where does it matter?

–

How does ‘protected execution’ or exception handling in q work?
