[stringtemplate-interest] String manipulations

[Jeremy Gray]

Terence, if such functions were to be provided in a standard library of
StringTemplate, wouldn't they essentially become considered part of the
language and start ST down the slippery slope that you've mentioned so
many times in your whitepapers and presentation materials?

I agree.  There should be a standard library of common web related  
transformations that come with StringTemplate so that there is no  
danger of a programmer opening up a huge hole to his model just to  
get these things. if they come with the application there is no way  
that they could be considered part of the developer's model even if  
they are computations.
