It took me awhile to get used to the dot operator, but what convinced me that it was a good choice is that also your own function can be broadcasted with function_names.(args). For example is you have a function process_a_file(in_filename,out_filename,parameter_value), then you can easily process also a list of files with process_a_file.(in_filenames,out_filenames,parameter_value) (if parameter_value is a scalar it gets broadcasted). I think that it is similar to numpy ufunc's but every function have this possibility. A useful macro is @. which allows you to write "@. A * B * C" instead of "A .* B .* C". Also the macro avoid the creation of an intermediate vector with A times B.
