Yes, we spoke about that some time ago. But my previous statement: no-loop error! seems to have the same beaviour which has any others error, when a function has at least the attribute []: is wrong: no-loop is uncatchable at all, and undisarmable, while orthers errors in functions with the attribute [] or [throw] can be catched and disarmed with a function wrapper. BTW, no-loop is the only one error wich show this behaviour. Neither Syntax error have its behaviour. I think that this could be related to the Break behaviour which ignores functions bound: loop 2 [print 1 do does [break]] ;= 1 Break does not requires [throw] to throw the break to the upper function. So a Break error can only happens at the higher level of code execution and never inside user code.
