You are aware of the fact that the maximum template depth C++ compilers
are required to support is limited?  If I remember correctly the number
was 17, and g++ enforces it (though provides a command-line parameter to
change the value).

Note that I discovered this issue by actually reaching this limit in a
real application.  Template depth can add up quite quickly, and making
libsigc++ compile is not enough because you have to leave room for user
code or even another library layer.
