[-- Attachment #1.1: Type: text/plain, Size: 287 bytes --]

Hello,

Attached a patch so repl-print becomes 'friendly' wrt large (huge) lists,
arrays, srfi-4 bytevectors ...

	I looked at the documentation but I could not spot anything/places where
	things would need to be changed wrt the above patch?

	Dito wrt tests?

Thanks,
David
