Hi Todd, you may use:
say "Yes" if "2018 xJul 7" ~~ /:i jul/; or: say "Yes" if "2018 xJul 7" ~~ m:i/jul/; In the second case, the adverb will apply to the whole pattern. In the first case, it will start to apply from the point where the adverb is. In this specific example, those two code samples will be equivalent since the adverb is at the beginning of the pattern. But it would make a difference if the adverb is somewhere else within the pattern. For example, this would fail: say "Yes" if "2018 xJul 7" ~~ m:i/j :i ul/; because the ignore case adverb would apply only on the 'ul' characters of the pattern, but not on the 'j'.
