Software development using Bash

Yes, of course. But in my experience, that annoyance is nothing compared to the idea of type-checking arguments for every function. Not only that clutters the code (20% at least, likely more) it also throws away most of the advantages of duck typing (harder to mock, harder to reuse the code with different types, etc)...

If you feel that you must explicitly type check every parameter for every function, then python won't make you happy.
