If you're wondering how to put this advice into practice, let's try to find out how to refer to C++'s UsdLuxDistantLight's Python API, specifically the UsdLuxDistantLight.GetAngleAttr() function:Look at the table above, and try to find the longest module name that exists in the name...
Find all the distinct subexpressions, and unify duplicates for a better cache hit ratio. Think about having the user (optionally) provide some representative input along with a grammar. We can then profile against it, see which expressions are worth caching, and annotate the grammar. Perhaps ther...

For simple public data attributes, it is best to expose just the attribute name, without complicated accessor/mutator methods. Keep in mind that Python provides an easy path to future enhancement, should you find that a simple data attribute needs to grow functional behavior. In that case, use...
