REPL fails without fetch API

[willglynn]

The REPL depends on fetch, an API for which "Can I use" reports 62.34% global availability. Support is better on desktop than on mobile, but in particular, fetch is not currently available in stable versions of Safari (WebKit #151937) on desktop or mobile.

There is an XHR-based fetch polyfill available.

Ah, wondering why REPL wasn't working. Ok.

As of e3221e3, this is working for me. Can you verify?

[willglynn]

Is this on the web? The live REPL currently shows Safari:

Svelte generates components that work in all modern JavaScript environments, but the Svelte compiler only runs in Node 6+ and browsers that support ES2015 features. Please reopen this page in a different browser such as Chrome.

I'm able to use the REPL on Safari (10.0.2) are you using an older version of Safari?

[willglynn]

A-ha! This machine is running Mac OS X 10.11.6/Safari version 9.1.2 (11601.7.7).

Ah, yes — we can close this issue. There's a separate one on the main repo (sveltejs/svelte#109) about getting the compiler to work in older environments
