avoid GCC -Wshadow warnings? about linalg HOT 2 CLOSED

Thanks for bringing this to my attention. I've gone ahead and made this change.

In my own code, I make the deliberate choice to shadow member variables with constructor parameter names, both for brevity and for safety, as it prevents the (surprisingly legal in standard C++?!) mistake of copy-constructing a member variable from itself.

However, I understand that users may wish to compile with strict sets of warnings, and may possibly wish to do so in conjunction with -Werror. A minor stylistic quibble would be a silly reason to turn away users.
