Summary:
This diff adds explicit type arguments to polymorphic function calls that do not constrain their types. This codemod will reduce the error burden that will come in a future version of flow.
This specific diff was generated by running:
```
flow codemod annotate-implicit-instantiations --write .
flow --json --pretty | jq '.errors | .[] | .message | .[] | .loc |.source' | sort | uniq | sed -e 's/"//g' | xargs hg revert
hg st -n | xargs grep "generated" | sed -e 's/:.*//g' | xargs hg revert
arc f
```
So these are the codemod results that introduced no new errors and no generated files.
