I would advocate that RLF is a very good approximation of what should
be RR. Perhaps one good direction to take is to try to make RLF
smarter and contains all constants from pi to cos(42^e).
Somehow, it already does (i.e. internally it keeps track of their
symbollic nature):

I reproduced the problem and finally narrowed the issue:
* bzip2 only produces a static lib,
* freetype 2.3.5 which we used to ship did not use bz2, whereas freetype
2.5.2 does.
* libtool refuses to put the static lib within the shared one (on Cygwin,
no problem on Linux).

Any number cos(rational x pi) is algebraic and equality of algebraic
numbers is decidable. Moreover, it is not because something is
undecidable that Sage should return a wrong answer. In that case, it
would be good to have a third party in comparison (either returning

I don't know. But anyways, contact Nathan Lawless if you are going to do
something with lattices.

Right, Anne set it to True, not yes. But shouldn't anything nonempty

So would a solution be to somehow roll back my version of freetype then? Or
would a more aggressive patch be required?

That should work unless something in Sage explicitely relies on new
features of freetype (if there are any).
Alright I found an old version of freetype in a spkg on here,

Hi,
I am not sure this is relevant to what I'd like to do:
I want a Lattice class for discrete subgroups of RR^n (I only care about
integer lattices actually) where i can do stuff like:
- sampling elements
- lattice reduction
- finding shortest vectors
- solving the closest vector problem

In retrospect, it appears that the OP should have asked the following
question: From the perspective of Sage, if Python were to have
another arithmetic operator (denoted @) with identical precedence
rules to *, would we use it for anything? Would we extend the
coercion model, etc.?
