Typing time is not a significant factor in programming. I've never met a programmer who can code as fast as he can type.
Meet some more. :p
Clarity, on the other hand is vital.
The problem with using verbose delimiters around actually english-like text is that it can start to mix with the text and that reduces clarity.
For example:
Rem Remove all the blocks in this list because it will end up overflowing End Rem
as opposed to
/' Remove all the blocks in this list because it will end up overflowing '/
See the difference? Something a lot of people miss.
