Assigning variable by name

[thykappa]

So I was coding a a block that would basicly act as an equivalent to +=, -=, *=, etc. in most other programming languages like so:

It would work like map (()) over [=], but for variables (think a more evolved form of change [] by ())

However, In order for me to do so, I need to be able to set a variable by its name but it wasn't working. I looked up in the forum why and I found a post from bh:

I'm not necessarily asking for it to be brought back (bh does make some good points) but at the very least is there a javascript function that will allow this?

Another technique it's good to know is the use of RUN or CALL to give blocks inputs they wouldn't otherwise accept:

This works in lots of other situations too.
