[IronPython] No ToString?

[Curt Hagenlocher]

This is a function of whether or not you've imported "clr" into the module.
Until you import clr, int objects will only have the methods of a Python
int.

PS f:\IronPython-2.0B2> .\ipy.exe
IronPython 2.0 Beta (2.0.0.2000) on .NET 2.0.50727.1434

>>> a = 42
>>> len(dir(a))
54
>>> import clr
>>> len(dir(a))
65
>>>

This is a property of the current module and not of the objects that you've
passed to it.  If "x.py" contains "def n(x): return len(dir(x))" and "y.py"
contains "import clr" followed by the same function, you get the following
output from using them:

PS f:\IronPython-2.0B2> .\ipy.exe
IronPython 2.0 Beta (2.0.0.2000) on .NET 2.0.50727.1434

>>> import x, y
>>> a = 42
>>> y.n(a)
65
>>> x.n(a)
54
>>>

So the solution is for you to add an "import clr" at the top of the module
where you're trying to use "ToString".
