    I see the workaround works in node as well. Thanks for the tip!

    $ node
    > function foo() {
    ... for (var i = 0; i < arguments.length; i++) {
    ..... console.log(arguments[i]);
    ..... }
    ... }
    undefined
    > foo(1,2)
    1
    2
    undefined
    > foo(100)
    100
    undefined
    > foo(1,2,3,4,5)
    1
    2
    3

    5
    undefined

    I was testing espruino on the Linux command line (while waiting for my boards to be shipped) and ran across this error. Is this a bug, or a feature?

    The source was cloned from github and compiled on Ubuntu 16.04.6 LTS. I got the same error on an OS X build as well. It was built with the following commands:

    export BOARD=LINUX
    source ./scripts/provision.sh $BOARD
     make clean && RELEASE=1 BOARD=$BOARD make
    

    I saw this post Functions with unknown amount of args. but I didn't get the same results.
