After some fights with debugger I think it's NOT possible that the .L
works the way you write. The direct cause is : the G__prerun is set to 1
during execution of the G_interpret_func ( see the line 2379 and following
of the file CINT_ifunc.c ).
On ".L t1.cxx" the G__prerun is set to 1 in line 1500 in file CINT_pause.c
in function G__process_cmd shortly before, in line 1501 of the same file,
the G__loadfile is called, which again ( line 1100 of CINT_loadfile.c )
sets G__prerun to 1 and then calls G__exec_statement ( line 1159 of the
CINT_loadfile.c ), which then ...
