I should admit, VALA code is simpler than pure C due to built-in GTK
classes handling. But I still don't trust it as VALA code is only part of
libfm which generates a lot of warnings still, rest of code is written in
C and is free of warnings, with all relevant warnings enabled.
And lxpanel2 requires pretty new version of VALA, released this year,
you cannot compile it on any older system.

I was overreacted about "cannot be debugged", I'm sorry. VALA doesn't
generate binary code, it generates C code, like this:
g_return_val_if_fail (_tmp18_ <= _tmp19_, NULL);
_tmp20_ = start;
_tmp21_ = end;
_tmp22_ = start;
_tmp23_ = g_strndup (((gchar*) self) + _tmp20_, (gsize) (_tmp21_ -
_tmp22_));
result = _tmp23_;
There is a lot of variables and all variables have names _tmpXXX and
after compiler optimizations it is pretty inconvenient to debug. In any
case you will have something under gdb, yes, but you rarely will get all
the data and you have to find relevant vala code by hands. I hope PCMan
can tell us more on the subject.
Cheers!
Andriy.
