LastCalc currently outputs numbers with commas, like 35,523,433 - however it cannot parse numbers with commas.
The issue is lists, is [123,456] a list with two numbers, 123 and 456, or the number 123456?
It's hard to think of a robust solution. eg. we could look out specifically for up to 3 digits, followed by one or more sets of 3 digits all separated by a comma, with no space. This may be sufficient, but could lead to misunderstandings in some circumstances.
