Christopher, you've never been noise.
Anyway, Guillaume's original concern was that #something(Stuff) used to work fin in pre-1.6 versions. But with the addition of the RuntimeMacro stuff in 1.6, it started throwing parse errors, because 1.6 has to treat everything that looks like a macro as if it were, etc.
The escaping attempt was just to try and circumvent the error. Of course, that still didn't work because #something was still not a macro. You have to remember in Velocity 1.x, it has always been the case that you do not ever escape just $ or #. What you escape are references, macros and directives which happen to start with either # or $. If you put a \ in front of something that looks like a reference, macro or directive, but is not, then it does nothing whatsoever.
Yes, this is confusing to most people who are used to just escaping characters. But it is far too late to change this in the 1.x series. When ever someone starts a 2.x branch, we can (and probably will) change that. But for now, #schmoo() will print #schmoo() and #validmacro() will print #validmacro(). There is no character escaping with \ and there never has been in Velocity. If you want character escaping, you have to use EscapeTool or poor man's style (#set( $H = '#' ) $
schmoo(). I've tried to clarify the docs on this for 1.6, but they could probably use more tweaking still.
