It can be used recursively to try to find a variable.
EXAMPLES
Note: In the followings examples, the _ between the { should be removed to make it work.
res={_{
a = 5;
function a1()
a2();
endf
function a0()
use a;
"a1="; a;
a2();
endf
function a2()
use a;
"a2="; a;
endf
function a3()
"a3="; a;
a2();
endf
a1();
a0();
a3();
}} will return res=a2=5a1=5a2=5a3=a2=5.
