Decoder with constants is throwing an exception. TypeError: (0 , _Result.Ok) is not a function

When trying to decode a string to one of 3 constants, am receiving an error TypeError: (0 , _Result.Ok) is not a function

Codepen example (open browser console to see error).

Snippet:

import { guard, either3, constant, Decoder } from "decoders";

const statusDecoder: Decoder<'complete' | 'closed' | 'failed'>
      = either3(constant<'complete'>('complete'), constant<'closed'>('closed'), constant<'failed'>('failed'));

const statusString = 'closed';

const status = guard(statusDecoder)(statusString);

console.log('Decoded:', status);

It just seems to break with the snowpack dev server (and skypack.dev). It works on my production environment so assume it has something to do with how they handle package caching / module reloading. Closing this issue because it seems like more of a “them” issue. Thanks for the awesome package @nvie.

Thx for taking the time to report a potential bug!
