Hello Dean,

Thanks for this explanation! I apologise for not replying sooner, but I wanted to look at the whole question with a fresh pair of eyes first. You are absolutely right:

my  @dirs.push: $_.split('/') for @paths;
say @dirs.perl;
[download]

shows:

[("", "aardvark", "bison", "camel", "dromedary").Seq, ("", "aardvark",
+ "bison", "camel", "dromedary", "elephant").Seq]
[download]

(i.e., 2 unconsumed Seq objects), but with .cache added to the split they are Lists:

[("", "aardvark", "bison", "camel", "dromedary"), ("", "aardvark", "bi
+son", "camel", "dromedary", "elephant")]
[download]

— and therefore can be iterated as often as needed.

Update:

upon consideration, using .cache may be more efficient since it is lazy

Where is this documented?

Thanks again,
