Re: [DESIGN] Aliases? (Was: RE: Re: I, too, miss tags.)

I don't understand what all the hubbub is all about. The change
request sounds simple enough:

* SVN already has the mnemonic "HEAD" which always points to the
latest revision.

* Some users would like to be able to create their own custom
mnemonics (for whatever purpose, that's up to them) which will point
to a revision of their choice.

* These same users are not asking to change the way tags are made in
SVN today. They just want an additional feature to SVN that other
users are free to ignore.

My question: How is the "HEAD" mnemonic implemented? Is it a variable
that is stored in the repository and gets updated every time a commit
happens? If so, would it be too big of a task to modify SVN such that
more of these variables can be made?

Or is "HEAD" nothing more than an instruction to the client to get the
latest revision. If so, would it be too big of a task to modify the
client such that it will allow the user to create additional
instructions that refer to certain revisions?
