>It's hard for me to understand how using indentation for scoping would be a "big problem" on a large/long-lived project. Editors screw up whitespace all the time. Many times when moving a block of code using cut and paste, it is easy to screw up the indenting. With brackets/braces, it is a simple thing to just reformat. With python, you have to make sure that you did not screw up the semantics (is this statement part of the if or not). A long-lived project likely undergoes a decent amount of refactoring and code reorganization. Having to worry about messing up the semantics of your code every time you move a block of code is not that great.
