The very first problem to solve is the lack of functions- that is the cornerstone for all other improvements. I suggest to use the C pre-compiler to generate function like structures and be the base for a more usable way to do D.

DTrace style: As there is no idiomatic defined ground rules for how to do style D code I will use this topic for proposals for how to make D more usable. Nothing set in stone- always room for improvements. Suggestions are welcome.

D have no way to name the arguments for a given syscall hook. They can only be accessed through the args array. I suggest the following style to enable naming of arguments:pic.twitter.com/0JKksOypTP

Before this I copy pasted the information into the source- why not define aliases at the same time? Relevant structures can be shown as comments without taking up additional space with this layout.

The reasoning for not having loops is the need for the D VM to set gurantees for execution time. Conditional looping can make that impossible. Instead we can repeat an action X times with a hard static maxium. Not pretty- but gets the job done

This is an example of an alternative to conditional looping. The algo implements a max len on strings. When reached- the middle characters will be dropped. Some dots are inserted instead when done- to communicate there have happened truncation.pic.twitter.com/Lmndu8a8k7

You can make a hook predicate saying only trigger when argument != 0x0. But what if that pointer points to something that can also be 0x0. And what about code duplication and nested casting? Avoid it all with the comma operatorpic.twitter.com/T6ZbOVASkH
