Hello, Yuan.

Ha!  No chance!  ;-(

I don't believe these proposed changes will increase discoverability to
any important extent.  More importantly, they will decrease the
usability of these functions, as they will be more of a hassle to type
in and (more importantly) make the functions they are in more difficult
to read.

I strongly object to those aliases which make the function name longer.
I particularly object to `re-match-after-point' for `looking-at'.  Not
only is it much longer, it lacks the instant readibility of looking-at,
and the slightly humorous notion of "looking", as though with ones eyes.
I particularly object to `re-matched-string', which has double the
number of syllables in it as the original.

As a small point, you've erased the commonality between
match-beginning/end and match-string.  This is a bad thing.

I hate your list.  ;-)  (Nothing personal in that.)

As long as people do not take for granted that introducing lots of
aliases is a good thing.  I believe it is not.
