Re: "dynamic message sends"

Hi ‘gettimothy’:

The immediate answer to your question is to use #’perform:’ like this:
	html tbsAlert
		perform: m;
		with: [ … ].
Note, however, that use of #’perform:’ is frowned-upon in some circles and you might be encouraged to find a more “object-oriented” way to do this.
