+$haystack.contains($needle)     # True if $haystack contains $needle
+$haystack.ends-with($needle)    # True if $haystack ends with $needle

+so $haystack ~~ /  $needle  /  # True if $haystack contains $needle
+so $haystack ~~ /  $needle $/  # True if $haystack ends with $needle

+# Using substr:

+substr($haystack, 0, $needle.chars) eq $needle  # True if $haystack starts with $needle
+substr($haystack, *-$needle.chars) eq $needle   # True if $haystack ends with $needle
+
+# Bonus task:
+
+$haystack.match($needle, :g)».from;  # List of all positions where $needle appears in $haystack
+$haystack.indices($needle :overlap); # Also find any overlapping instances of $needle in $haystack
