The confusing thing here is that the macro text substitution process is performed repeatedly until no more substitutions are found. Thus, in this example, the string "$(currentTiddler)$" is passed as a parameter to the macro. The first text substitution replaces the $_$ with that parameter value, yielding "This is a $(currentTiddler)$". The second text substitution replaces "$(currentTiddler)$" with the value of the variable "currentTiddler". Note that text substitution is rarely the best way to accomplish things. It was implemented early in TW5's life as a bit of a hack to allow certain complex operations to be performed in order to build the UI. There are quite a number of gotchas with its use. The wikitext language has been enhanced considerably since then, and now there are better primitives for most situations.
