Even if String-type needs length as first argument, column(String,  
length=20) throw's an execption when defining columns on ActiveMapper

class User(ActiveMapper):
     class mapping:
         username = column(String, length=20)

Exception:
   File "build/bdist.darwin-8.7.0-Power_Macintosh/egg/sqlalchemy/ 
schema.py", line 341, in __init__
sqlalchemy.exceptions.ArgumentError: Unknown arguments passed to  
Column: ['length']

This also blocks implementing recently discussed validations to  
columns, because they would need some extra keyword arguments for sure.


With kind regards,
