No warning message when using Runtime:setCheckGlobals( true ) ?

Hi

I’ve just tried to use Runtime:setCheckGlobals( true ) … which sound great …!

but im getting no warning messages? i can just set Globals as normal.

Runtime:setCheckGlobals( true ) ThisIsAGlobal= "I am a GLOBAL" -- print globals for k,v in pairs( \_G ) do print( k .. " => ", v ) end -- ThisIsAGlobal is in the Global Table, no console warning ?? is it me ?

Im using daily build 2016.2997 (downloaded about 10 minutes ago)

Thanks in advance for any advice.
