I need to build a detail dictionary with key/values from point attributes.

Ideally something like this in a point wrangle would work:
setdetailattrib(0, d@mydict[itoa(@ptnum)], myvalue, "append");
The offender is the second argument of course, as it is expecting a string.

So I managed to do it from a detail wrangle with a for-loop.
My only question: is there a more direct way to assign the key values without using the intermediate dummy array?

for(int i=0; i<@numpt; i++)
{
    string key = point(0, "key", i);
    int dummy[] = d@mydict[key];
    append(dummy, i);
    d@mydict[key] = dummy;
}

Can also be done via set() and insert():

In a detail wrangle:

string names[] = {'foo','bar','foobar'};
float vals[] = {.123,.234,.345};

d@myDict;

for( int i = 0; i < len( names); i++)
{

    string thisName = names[i];
    float thisVal = vals[i];
    
    insert(d@myDict,set( thisName, thisVal));
    
}
