Something's wrong with the makefiles. I checked out the Subversion
trunkhttp://svn.freepascal.org/svn/fpc/trunk/and ran sudo make
install.
Partway through the process, when I run fpc in a new terminal, I get:
$ fpc
Free Pascal Compiler version 2.7.1
But when make finishes installing, I run fpc
I forcibly sudo cp ppc386 /usr/local/bin/fpc, mitigating the issue. Yeah,
something in the makefile installation process is definitely moving over an
older version. (I deleted the whole directory for the v2.4.4 subversion, so
that's not the problem.)

Sven, recap: I want to make a GenArray function that returns an array
populated by a generator anonymous function. For example, GenString would
generate a random string by doing GenArray(GenChar). Users could create
their own generators, e.g. GenTree wrapping around GenArray(GenLeaf),

Sven, awesome! Looks like FPC will be getting some exciting features in the
near future.
Jonas, make install does, however, overwrite /usr/local/bin/fpc, which is
not a symlink, with an old version during install. Try running fpc -version
halfway and after make install.

Only time will tell whether it's the near future. Also these features
are meant to be Delphi compatible (except the point that FPC will
support global
Jonas: Thanks, I'll use fpc -iV from now on.
But make install still puts an fpc binary in /usr/local/bin that reports
2.7.1 and then overwrites *something* so that a second fpc call reports
2.4.4.

No need to wait, checkout the fixes_2_6 branch, which is currently at
version 2.5.1, but will become the v2.6.0 release. This also means you

Ouch, sorry. I read about generic procedural types at New
features trunk wiki page and thought it was what OP need.
Andrew, I apologize for misinformation and thanks Sven for
correcting me.
Thrice is designed to work for *any* array type, e.g. arrays of arrays of
arrays of bytes. Even if I hardcoded several thousand possible types, Thrice
wouldn't work for custom user types.
If you do find a way to make this work, please let me know.

There is no built in list type, generic or not, and no way to define new
operators. All
Can this be done with arrays? I didn't mean to be too specific; I'd be happy
with any generic collection that could do this.
