Modernize grammar syntax
Raw
gram.txt
There are several instances of some old regex syntax in the current rakudo grammar.
From a brief answer by @timotimo, I'm assuming those instances can be changed to:
<tok>**1 [1 use; require one instance of the token?; change to =>] <tok>
<tok>**0..1 [17 uses; require none or one?; change to =>] <tok>?
