console.log(1,2,3) will show all three values. Similarly the log point 1,2,3 should show all three values.

1526557 changed the default behavior from using console.log to evaluating the expression and using the return value.

One of the common usecases for multiple values is a log with a label and a value. e.g. addBreakpoint ${bp}

we could get this behavior by using an array to capture all of the values [${log}]

This could potentially have some issues in terms of error messages, but overall is fine.

This is the behavior from other log point implementations as well and helps to avoid string concatenations/templating, so +1 to align this; maybe even making this a stretch goal for M1.
