Re: Re: geant: notion of local variables

I agree that  <local ../> would be nicer than <setlocal ... />

but then .. do we consider <local ../> as local declaration, as 
<argument ... />
and in this case  <set /> and <unset />  would find itself, if they 
apply to local or global ?
And if we use <local /> as declaration, do we allow  unset variable ?
I mean ...

    <local name="test" />
    <echo message="$$test is not set" unless="$test" />
in this case I guess it is better to allow not set local variable.

we could even use  <local name="test" value="foobar" />  to initialize 
directly

If this is fill everyone's expectation, I can change my patch to have this.

and yes, local will bring better geant scripts :)
more than once, I got trapped by those awful global variable ;)

of course I would prefer to have   <set .. /> by default for local 
variables, and use  a <global name="varname" /> 
but this would break existing code...
