Changes (by kcrisman):
* priority: major => minor
Comment:
This is still true, and syntax is also deprecated.
{{{

Substitution using function-call syntax and unnamed arguments is
deprecated and will be removed from a future release of Sage; you can use
named arguments instead, like EXPR(x=..., y=...)
