setTimeout() broken... not exactly, but if in upload and...

Not sure what's going on - is the code uploading correctly, or do you have something else saved in Espruino? I just ran all 3, on Pico and original boards using the 1v79 release from the website and got:

 _____                 _

>echo(0);

  "f1(): "
 ]
[
  "f2(): "
 ]
[
  "f3(): "
 ]
=undefined

[
  "fE(): "
 ]

Which is exactly what you'd expect?
