> Changing a declaration to have a different type then means you've got endless cascading identifiers that need to be redone.
This is actually a good thing, every mention of that identifier is a place that you might need to adapt for the new type. Hungarian notation is an excellent coping mechanism when you have to use compilers that don't do their own type checking - which used to be a huge issue when Hungarian notation was current.
On balance, it isn't a good thing. Having high refactoring costs means:
1. you become reluctant to do it
2. lots of diffs cluttering up your git history. I like my git history to be fairly narrowly targeted.
I don't use languages that don't do type checking. Microsoft uses Hungarian notation on their C interface and example code.
