Well, this needs to be changed. This makes sense for definite integrals,
but not for indefinite integrals, where the integration variable is free.

Yes that's definitely the problem.
I've just checked that everything works ok with Python32 under Win64 and it
does.
So although 64bit is the future it's not

There's some complex and implementation-dependent interaction between
__slots__ and metaclasses. I'm not sure how this can be fixed except by

I didn't read the issue too closely. Is there no way to make a win64
installer?
Also, saying Python32 is a bad way to say 32-bit Python, as it sounds
like Python 3.2.

Do you know what specifically is implementation specific?
Perhaps we should ask the Jython guys for help with this.

I asked on the jython-users mailing list

see if that helps any.

Hi,
For those who've not read my latest blog, I'm working on
implementing a new structure for the matrices module of sympy.
I faced many decision problems while doing so, like what should be
named what and what should be where.
Should matrix and linear algebra be separated ?
So,
Hi everyone.
I'm concerned about how subs() handles dictionaries, in which
the values of the dict contain some of the keys, such as
(x**2+y**3).subs({x: a*x+b*y, y: b*x-a*y})
Would it be preferable that the result is
(a*x+b*y)**2+(b*x-a*y)**3
? Right now subs() re-substitues terms which

First off, if you want an explicit order of substitution, you should
not use a dictionary. Subs also allows the [(old, new), ...] syntax,
which lets you define a specific order.
But even in this case, it will perform the substitution iteratively.
This is actually a useful feature. For example,
