Wanting to take all the elements from a list starting at position x to
the end is pretty hard when the list is dynamic, so $#list cannot be
used, nor can index -1

Why cannot we use open range operators in this case?

Both [n ..] and [n ...] are currently syntax errors

$ perl -wE'say for [qw( a b c d )]->[2 ..]'
syntax error at -e line 1, near "..]"
Execution of -e aborted due to compilation errors.
$ perl -wE'say for [qw( a b c d )]->[2 ...]'
syntax error at -e line 1, near "...]"
Execution of -e aborted due to compilation errors.

either of the above could be defined to return qw(c d)
