How can I execute the current line as Vim EX commands?

Question

Say I\'m editing my _vimrc file and I\'ve just added a couple of lines, for instance a new key mapping. I don\'t want to reload the whole file (:so %

To execute the current line as an ex command, you may also use:

yy:@"

This will yank the current line to the "-register and execute it. I don't think it is too much typing.
