[Numpy-discussion] request for new array method: arr.abs()

numpy renamed the *function* abs to absolute.
Most functions like mean, min, max, average, ...
have an equivalent array *method*.
Why is absolute left out ?
I think it should be added .
Furthermore, looking at some line of code that have multiple calls to
absolute [ like f(absolute(a), absolute(b), absolute(c)) ]
I think "some people" might prefer less typing and less reading,
like f( a.abs(), b.abs(), c.abs() ).
One could even consider not requiring the "function call" parenthesis '()' at
all - but I don't know about further implications that might have.
PS: is there any performace hit in using the built-in abs function ?
