Arguments may have default values (name=expr). Method_name may be operators (see above). The method definitions can not be nested. Methods may override following operators: .., |, ^, &, <=>, ==, ===, =~, >, >=, <, <=, +, -, *, /, %, **, <<, >>, ~, +@, -@...
is to run the test suite, find the last method which must receive keyword arguments for each place where the test suite fails, and use puts nil, caller, nil there. Then check that each method/block on the call chain which must delegate keywords is correctly marked with ruby2_keywords. [...

Then, when a reload is triggered, just acquire the lock for writing in order to execute the method call safely:MyFramework::RELOAD_RW_LOCK.with_write_lock do loader.reload endOn reloading, client code has to update anything that would otherwise be storing a stale object. For example, if ...
By default, rubyzip will not overwrite files if they already exist inside of the extracted path. To change this behavior, you may specify a configuration option like so: Zip.on_exists_proc=true If you're using rubyzip with rails, consider placing this snippet of code in an initializer file...
