I asked this already but with a different subject heading, so people may have missed it.
BackslashOperator is defined in "sage/misc/misc.py", and the preparser converts "A \ b" to the appropriate Python code. The docstring for BackslashOperator says "Implements Matlab-style backslash operator for solving systems A \ b". This is not used much: for matrices, matroids, and a tiny bit (at least in the Sage library) for binary trees. Should we deprecate it? Arguments for deprecation: the less we rely on the preparser, the better (at least as far as easing a transition between Python and Sage, for instance). The backslash operator is not in wide use in Sage. Currently its implementation breaks the standard Python use of "\" as a line-continuation marker. Arguments against deprecation: it provides a convenient shorthand, and people may be familiar with it from Matlab or other systems. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
