Guards idea

[kalagin]

some time ago I was discussing the possibility of typed validation of childrens and components that are passed through props.

my discussion finish with creating this package https://github.com/lulldev/prop-types-required-nodes, where in dev mode and prop-types we can check specific components in props. After that i research type-safe realisation but i was not able to narrow the ReactElement type.

what you think about it? sometimes i play with https://github.com/hyperhype/hyperscript and types.
final idea: strict jsx like arche or hyperscript with garanties in props and make jsx testable on function level (if we had nested typed functions - we can create structure to expect it in tests)
