I just finished adding type annotations to a 10-year old python codebase (for type-checking with the magnificent mypy).

I had to do stuff like this:

find . -type f -iname \*A_mapper.py | while read ANS ; do
    cat "$ANS" | \
        sed 's/def OnBasic(\([^,:]*\), \([^,:]*\), \([^,:]*\)):$/def OnBasic(\1: str, \2: AsnBasicNode, \3: AST_Leaftypes) -> None:/' | \
        sed 's/def OnChoice(\([^,:]*\), \([^,:]*\), \([^,:]*\)):$/def OnChoice(\1: str, \2: AsnChoice, \3: AST_Leaftypes) -> None:/' | \

sed 's/def OnSequence(([^,:]), ([^,:]), ([^,:]*)):$/def OnSequence(\1: str, \2: AsnSequenceOrSet, \3: AST_Leaftypes) -> None:/' | \

WHAT:  A very simple example of redux + redux-simple-router using Typescript.

WHY: The official example found here: https://github.com/rackt/redux-simple-router/tree/1.0.2/examples/basic has problems:
1) it is spread over many files making it very hard to "skim"
2) it is organized by function, not by feature.  (Example: learning "how to manipulate redux state" is spread over 5 files in 4 folders)
3) there are no comments explaining what's going on/why.
