How to use Lasso ds type to return the found count of a result set

ds->found_count

local(d) = ds(::mysqlds,'localhost',::database.table,'username','password')
local(sql) = `
    SELECT *
    FROM table
    WHERE id > 0;
`
local(rs) = #d->sql(#sql)->results
if(#rs->size > 0) => {
    if (#rs->get(1)->found_count) => {^
        'at least 1 record'
    else
        'no records'
    ^}
}

// or for brevity

if (#d->sql(#sql)->found) => {^
    'at least 1 record'
else
    'no records'
^}

// now with local

local(r) = #d->sql(#sql)
if (#r->found) => {^
    'at least 1 record'
    // do stuff with #r
else
    'no records'
^}
