is it just a joke, or you really think minifiers are stupid things? :p
if its for any Platform minification / obfuscation, in another thread i was advocating that it would be more efficient to have it at compiler level, instead of replicating the work at each target levels. even if you still can have complementary Tools for second pass as specific target Tools.
compiler could give errors about Reflect usage which is incompatible with minification (when field name parameter is not a static string or to ambiguous)
