[stringtemplate-interest] [ST4] Warning when no variables declared in anonymous template

[Matthieu Wipliez]

Hi,

the following

<values: {something}; separator="\n">

causes the following error:
"anonymous template has 0 arg(s) but mapped across 1 value(s)"

I think this error is a bit strange, because I don't need to declare a variable 
in this case, and I believe this is allowed by the grammar.

Declaring a variable in the template solves the problem, but I find it strange 
to declare a variable I know I won't need:

<values: {unused | something}; separator="\n">

Cheers
Matthieu
