A very good reason

In a recent post in this thread, Savdeep Sethi pointed out that at least
for certain computations
LiE is much faster than Sage for decomposing tensor powers of
representations. In analyzing
why this is true, I tried replacing the current algorithm, which is the
product_on_basis method
of WeylCha

There is already an optional LiE spkg for Sage [1]. I don't know anything
about it, for example whether it even builds. But that would perhaps be a
place to start.

Currently sage can do most everything that LiE
