[stringtemplate-interest] Separation of View and Biz Logic

Hi All,
We are migrating some velocity templates to ST, and in the velocity
templates we had been calling some static utility methods to do
things like uppercase the first char, lowercase the first cahr
transform a camel case word (like employeeStartDate) into a constant
form (like EMPLOYEE_START_DATE)--things like that. Rather than make
separate variable for each form, we were thinking of making a utility
class whose instances take a String. Then there are get methods for
each of the permutations, like getWithFirstUpper(), getWithFirstLower
(), getInCamelCase(), getInConstantForm(), etc. So it could be
accessed inside an ST template with employeeStartDate.withFirstUpper
or employeeStartDate.inConstantForm. The toString method on this
object would just return the String passed to the constructor. We
would encapsulate relevant String variables inside instances of this
class, then pass those to the template instead of the raw Strings.
This seems perfectly reasonable way to do this, but I wanted to check
whether it violated anyone's sense of strict separation between view
and biz logic.
Thanks.
Bill
