Comment (by vbraun):
Oh you mean the good old `var(', '.join(['x{0}'.format(i) for i in
range(10)]))` trick. Calculus freshmen are going to love your class... In
any case I don't mind having a way to inject multiple variables at once,
but something like
{{{
sage: SR.inject_variables('x, y')
sage: SR.inject_variables('x', 'y') # strings to variable names
sage: SR.inject_variables('x{i}', i=range(10)) # use keyword arguments
to format
sage: SR.inject_variables(ex) # inject all of ex.variables()
}}}
would probably be a lot better.
