I would hate that same code lead to different results depending on a 
global preference set somewhere in the image...

Unless you use:

a) a compiler directive in a pragma (i know, Lukas don't like this use 
of annotations)

	<thisCompiler literalAreMutable: false>
	WriteStream on: 'test'.

b) a message explicitely stating the literal should be mutable.

	WriteStream on: 'test' beMutable.
