Stream.expectNumber

If the string begins with one or more contiguous character(s) that could be interpreted as a number, the stream skips to the end of that number sequence and parsing continues.

"1234 items" is passed so the remaining stream is "items"

"1,234 items" is passed so the remaining stream is ",234 items"

Note how the presence of a formatting comma breaks an otherwise continuous number sequence.
