Hmm I'm getting SillyError(tm) now:
AttributeError: 'module' object has no attribute 'input'
${h.input('user3', value=initstr)}
I've created HelloWorld project per Pylons Book instructions, do I need
to enable helpers explicitly somehow somewhere?

That's what reading tutorials and books gets you, I got into habit of
using try .. except blocks and now I have to explicitly remember to get
rid of them where possible. Documentation should be read as last resort. :-)

Thanks, I will consider this, though I have looked at Formish today and
it looks *freezing cool*, incl. automatic generation of error HTML boxes
if invalid values were entered by user, and custom validators, like this:
class LessThan5(validatish.Validator):
def __call__(value):
if value is not None and value < 5:
raise validatish.Invalid('less than 5')
...
schemaish.Float(validator=LessThan5())
