The question isn't what "may" happen, but what routinely does happen for you. If typos are even a significant problem in your code then the solution is to type more slowly, have your IDE flag unknown symbols, use autocomplete, etc. As a solution to this problem, strong typing is both disproportionate and inadequate.
