I started my first major hosta plantings in full sun, buying specimens from Diana Grenfell who was an expert on hostas and hemerocallis. They did so well that after just 2 or 3 years I had to lift and divide the lot.
There is a small hosta called Gold Edger which is happy in sunshine and, as the name suggests, good for edging beds. Sum and Substance is a large leaved gold coloured hosta that needs sun to keep its foliage yellow, rather than green. Gold Regal, Gold Standard and Sundance are other possibilities for a sunny site.
The hostas with fragrant flowers need sun to develop the perfume - Fragrant Bouquet, Royal Standard, Honeybells. Invincible has glossy green leaves and perfumed flowers and is supposed to be slug resistant but in my garden it's the first one they go for, whether in the ground or in a pot.
As Dove says, you do need to make sure your soil is beefed up with plenty of organic matter - garden compost, well rotted manure etc - for moisture retention. Avoid white and cream variegations as these scorch in the sun.
