Awesome! Is it possible to override a global from /within/ a method (e.g. in
a test)?
I think at the class level by manipulating that class compiler
Yes. You can override the class side method:

in Behaviour, it is defined as

compiler
	"Answer a compiler appropriate for source methods of this class."

	^self compilerClass new
		environment: self environment;
		class: self

so you can just 

compiler
	âChange the compiler environment "

	^super compiler
		environment: self myEnvironment

and it should work.

an a per method bases, we can only manipulate the compiler via Pragmas to set options:

	<compilerOptions: #(+ optionInlineTimesRepeat)>

for example.
...
(and
forcing a method recompile...)
indeed.. I still believe that we should late-bind global access :-)
