Support yield keyword

[ivan-aksamentov]

I would like to see yield keyword support for Python, Javascript and Typescript generators. Note that Javascript also has yield* for async generators. Other languages having iterators/generators (for example C#, Rust, PHP) may also enjoy having this implemented.

In order to increase compatibility and reduce noise, the yield keyword highlighting may be added as an optional feature, disabled by default, that can be enabled with a checkbox in settings. It would be also nice to have a separate color choice option (with an option to inherit color from the return one).

Creating a separate plugin-sibling for yield, instead of adding this functionality into current plugin, may be an option too.

• Python docs - yield
• MDN - yield
• MDN - yield*
• C# reference - yield
• Rust - generators
• PHP - Generator syntax

^{Thanks for this great plugin!}

Oh btw, C# support is in backlog. No idea if I will ever support it...
