Toot

[#]Rakulang grammar question. Given something like:

[#] Ex. 1
grammar CSV {
    TOP {} # ??
    token column { [ '"' ]? .* \, [ '"']? }
}

[#] Ex. 2
grammar USD {
    TOP {} # ??
    token dollars { \d ** 3 [',']? } 
    token cents   { \. \d ** 2     }
}

1. How do I tell the grammar's TOP that a given token could potentially repeat an arbitrary number of times?

2. Can I mix in range validation somehow? So that 1,234.56 is a valid capture but 0,123.45 is not.
