Are there any general performance tips that you've come across that aren't
immediately obvious?
Stuff like:
* Sequence / String assignment uses copying semantics (and avoiding with
{.shallow.} or ref)
* Avoiding hidden allocations
* Good patterns for submitting easily parallelizable stuff to the threadpool
* Effectively using slices to avoid allocations
* Append vs add vs '&' for sequences and strings
If performance is an issue I usually just try to profile with Apple's profiling
tools in XCode or the equivalent in Linux, but I don't feel like I've developed
a sense yet for how to write really idiomatic, performant code "the first time".
If nothing else, it would be a good blog post ;)
