I'm looking to deal with a stream of data that includes a structured, 
variable-length header followed by a (potentially large) binary blob. I'd like 
to parse only the header while leaving the stream (can be a java stream or NIO 
channel, whichever works best) positioned at the start of the binary blob. Can 
Buffy currently do this?

About naming: is the -type prefix to the built-in data types (string-type, etc) 
really necessary, given they're already grouped in the buffy.types namespace? 
I'd prefer to be able to write t/string, t/int32 and so on, personally.
