I can't find the prepare() code but I thought that it would work by
string substitution, replacing each ? with an (appropriately quoted)
value.  Or by creating a temporary stored proc as mentioned in the
docs, again just brute-force replacing ? with parameter names.

Do you mean it really tries to parse the SQL and work out the
procedure name and the names of each parameter?
