"foobarbaz".comb.Array.splice(3,1,"X").join.say;
# Output: b

# Issue: splice returns what was cut out, not the result.

# Solution: Keep the array of characters around for later.
my @a = "foobarbaz".comb; @a.splice(3,1,"X"); @a.join.say;
# Output: fooXarbaz

# Don't want to introduce a local variable for this?
