Many of us would consider that a complement.

Yep, it's a bog-standard OOP language.  The killer feature is its tight 
integration with GObject.


And the only point I remember is its ABI compatible with C, which 
also limit its language possibility.


I'm pretty sure both Vala and C are Turing-complete. :)

I think it's would rather better to spend time solving the problem 
like gtkmm can't provide a function like 
"builder.signal_connect(this)" to auto connect the signals defined in 
glade XML files rather than start another project to reinvent the 
wheel.


It sounds like you're looking for Gtk.Builder.connect_signals() [1].  
It exists, but not in the gtkmm bindings.  This suggests to me that the 
problem is C++, not GTK.  There is a bug report [2], though, so jump in 
and get it fixed.

I heard Vala before and I read the tutorial and some sample code of Vala today.


Silence...

Sorry again, I am a bit excited.
