Unexpected named exports, related to spread operator

[duncanbeevers]

It appears function parameters are jumping into the list of module exports.
swc version 0.1.7

Input

export const good = {
  a(bad1) {
    (...bad2) => { };
  }
};

Output

var _ref = {
    a: function(bad1) {
        (function() {
            for(var _len = arguments.length, bad2 = new Array(_len), _key = 0; _key < _len; _key++){
                bad2['_key'] = arguments['_key'];
            }
        });
    }
}, good = _ref;
export { good, bad1, bad2 }

Note the unexpected bad1, and bad2 exports.

Fixed with swc@1.0.6

@kdy1 Did this issue regress? I'm seeing similar incorrect behavior.

Input

export const good = {
  a(bad1) {
    (...bad2) => { };
  }
};

Output

var good = {
    a: function(bad1) {
        (function() {
            for(var _len = arguments.length, bad2 = new Array(_len), _key = 0; _key < _len; _key++){
                bad2['_key'] = arguments['_key'];
            }
        });
    }
};
export { good, bad1, bad2 }

@duncanbeevers There is a test for it, and it passes.

swc/ecmascript/transforms/src/modules/common_js/tests.rs

Lines 56 to 82 in c1a3cc5

What is your config? (I mean .swcrc and version of the swc)

[duncanbeevers]

I did a rebuild with a linked c1a3cc5
In my project I did an npm link swc

swc --version displays 0.1.7.

I get the same results running with --no-swcrc.

My project .swcrc, such as it is, is very simple
