Do and Block Params expressions [Parser]

Feature Request

Describe the solution you’d like I suggest making do and block param expressions. do expression:

do {
    // code
}

And block params:

something {
    // code
}
something(someValue) {
    // code
}
something(someValue) // one line of code
something // one line of code
a.b['c']('d')('e') {
    // code
}

do expression is already in stage 1 and so is Block params. So why not adding it? Pipeline operator is in stage 1, yet here we have it in Babel. I think that at least do expressions should be in Babel.

• Block Params
• Do expressions

I remember that some tc39 members said that that proposal is unlikely to proceed as-is.

I’m closing this issue; not because we don’t want to support them, but becasue we already track proposals implementation status in another repository: https://github.com/babel/proposals/issues/53
