"Realizing how narrow my definition of pies is, defined by a very narrow view and sensibility regarding crust. Especially with regard to American pies, which includes Central and South America and Native American with their cross cultural traditions of empanadas, samosas, chimichangas, baked or fried, made with corn or wheat flour, or grated yucca vs potato "crusts."

Most of what you cited are forms of dumplings... a world wide way of preparing food using local ingredients.

Pie & tarts.... breads... pastries... pastas(shaped or filled) and then dumplings which can include filled dough or any number of varietions. boy... am I hankering for some nice dim sum right now... :)
