The plain name; also looks like a useless expression-statement.
Beyond this, I'm concerned that per-instance properties need initializers that
use constructor parameters. So they ought to be initialized in the constructor.
Whether they can be declared outside the constructor is a separate issue.
Perhaps if they have constant or constructor-invariant initializers, they can
be initialized where declared too.
But declarations should look different from expressions. The alternative we
keep returning to is the property assignment sub-grammar of object literals,
which would want
new:
numAttacks: 0;
with a semicolon not a comma.
Anyway, this is a detail, and we could even defer it and still have a better
class proposal using your C++-inspired label idea. I'm quite taken with that!
