Hi -

Just stumbled over this:

	self should:[Heap new first] raise: Error.

Right? However, in Squeak 3.9 and later it doesn't. From the 3.9 change 
log it appears it got introduced here:

	------
	Change Set:		decompileBlock-md
	Date:			24 November 2005
	Author:			Marcus Denker
	A simplification for BlockContext>>decompileBlock:
	The Method got the tempNames by compiling the source of the method. This
	is already implemented in methodNode tempNames... thus not needed here.
	------
	remove emptycheck for Heap>>fist and SequencableCollection
	#first, #last, #middle
	------

but no comment as to why. Any insights into the reasons for this change 
anyone?

Cheers,
   - Andreas
