My problem, usually, has been that when using a for loop on a series
which gets altered, the loop fails to access the altered series/block, but
continues to use the original. How do I go around this? (Ie, if I have [a
b c d] and I run a for loop through it, when the loop reaches c, I want to
append [e f g] to the block, and continue running the loop through e f g...)
Does this make sense? Thanks everyone.
