:ex (:exhaustive)

This adverb finds as many substrings as possible, taking into account every posibility, including overlapping values and substrings of different lengths. This partially resembles the behavior of a regex with the :ov adverb but does not select the longest matches.

Let us test this adverb with the same pattern /1.*1/ on the value of pi (but this time, we'll take a shorter string):

my $pi = '3.141592653589793238462643383279502884197169';my @a = $pi ~~ m:g:ex/1.*1/;say ~@a;

We took a shorter version to save a bit of space in the output:

1415926535897932384626433832795028841971 1415926535897932384626433832795028841 141 15926535897932384626433832795028841971 15926535897932384626433832795028841 1971
