TypeScript Version: 3.8.0-dev.20191228
Search Terms: parameter property private
Code

class C {
    constructor(private #prop: number) {}
}

Expected behavior:

Maybe Parameter properties cannot have a private name.

Actual behavior:

A parameter property is only allowed in a constructor implementation.(2369)
Parameter '(Missing)' implicitly has an 'any' type.(7006)
Identifier expected.(1003)
';' expected.(1005)
Unexpected token. A constructor, method, accessor, or property was expected.(1068)
