The mistake is the block around the b.
or: in DynamicGroup is defined as
or: aGroup
and if you do not put a block, the compiler will not optimise or: —> it will be
send.
(and the or: in DynamicGroup will just raise an error when it gets passed a
block, it
expects a group).
But there is a second error: the mustBeBooleanInMagic: normally should work.
(the VM executes the optimised construct —> raised an exception —> we recompile
the expression with no optimisation -> execute.
There is tiny bug there (it should be #methodNode).
I will commit a fix for that…
(I hope this is understandable.. as two bugs are involved this might be a bit
complex.
