Issue defining a defrecord protocol method named "clear"
Key details
Description
There seems to be a problem in trying to define a protocol with a method named "clear"
(defprotocol PClear (clear [o])) => PClear
(defrecord Foo [] PClear (clear [o] o)) => CompilerException java.lang.ClassFormatError: Duplicate method name&signature in class file xxxx/Foo, compiling😞NO_SOURCE_PATH:1:1)
I assume this is due to a name conflict with the Java method Collection.clear() in the underlying implementation. However the error is very unclear about this, and the potential for conflict appears to be undocumented as far as I can see.
There seem to be two possible approaches to fixing this: a) Disallow the use of "clear" as a protocol method name (in which case the error should be more informative, and the rule should be documented) b) Find a way to support this in the class file format (possibly by overloading on JVM return types, since Collection.clear() returns void??)
