When a block of code is to be omitted (temporarily or semi-permanently)
it's convenient to have something like /* and */ as comment markers.

It's also convenient to have comment markers for long blocks of comments.

Live parsing editors are useful tools, because they highlight
code segments (including comments).

The above quotation is mere hype, like the author's justification for omitting
exponentiation in Pascal, somehow more convenient to use log and exp instead!
