Agreed. A program is made of names, these names are of the utmost importance. For understanding, and also for searchability.

I do a lot of code reviews, and one of the main things I ask for, after bug fixes, is renaming things for readers to understand at first read unambiguously and to match the various conventions we use throughout the codebase.

Ex: new dev wrote "updateFoo()" for a method converting a domain thing "foo" from its type in layer "a" to its type in layer "b", so I asked him to use "convertFoo_aToB()" instead.
