Related matter;
I recall on my own learning journey that much of the Tiddlywiki.com
documentation had ONLY example with literals
eg;
<<macro tiddlername subtiddler>>
The above is true but limited!
More often that not the user wishes to provide the value "tiddlername"
programmatically, such as a result of concatenation.
Of course we learn that to do so using the macrocall Widget but this
suggests to me every macro documented should have is variouse formes of
"macrocall" documented as well.
eg `<<tag tagname>>` <$macrocall $name=tag tag={{!!mytag}}/>
With a note on how to find the names of parameters because you cant provide
parameters without a name in macrocalls.
*My point this more useful form of every macro is rarely documented.*
Regards
Tony
