I've posted an initial version of "sweet.scm" on SourceForge,
which is an initial implementation of "sweet-expressions"
(in Scheme, in this case). This lets you use indentation,
infix, and name-ending like myfunc(a). MIT license.
It's in the subversion trunk for "readable". To get it,
have a subversion client installed, and type:
svn co https://svn.sourceforge.net/svnroot/readable/trunk readable-trunk
('readable-trunk' is a working directory that will be created and have
the files placed there).
If you want to quickly glance through it, without installing
any software other than a web browser, you can look at it here:
