You still have to interact through a tlist though. [?] Where as a TMap
you can just do:
TMap tm;
tm.Add(new TObjString("bob"), new TObjString("smith"));
cout << ((TObjString *)tm.GetValue(new TObjString("bob")))->GetString()
<< endl; // apart from the leak in the second new bob.
and it's even easier once I wrap it in a char friendly manner. (below)

Is there much memory overhead with TMap? I was also thinking of
implementing a handy PHP construct:
<input type="text" name="user[username]" >
<input type="text" name="user[password]" >
//in php
<?php
print_r($user); //PHP converts user[*] to array
//prints out user[username] => (value of user[username] input from form)
//user[password] => (value of user[password] input from form)
?>
So in Carrot this could come across as: (not syntactically complete)
if( ap.GetVars("GET")->IsMap("user") )
{
TMap *user = ap.GetVars("GET")->GetValue("user");
cout << user.GetValue("username") << endl;
cout << user.GetValue("password") << endl;
}
The details of what ap.GetVars returns would have to be worked out.
What ever object is returned would have to be aware of what type of
object it was storing
Just a thought anyway :-)
Thanks Valeriy

BTW, did you manage to get TApacheUpload working from the ALLVar.C script?
