I extended WriteStream in VA Smalltalk with:

onStringOfSize: anInt
	"Answer a new instance to write stream on a string of size anInt."

	^self on: (String new: anInt).

so that when I know I need a large stream, I can give it a good starting
size.

I do kind of like extending String with writeStream (thinking about it) so
one could write:

	(String new: anInt) writeStream
