I wonder how often this is a bottleneck in code performance.

Also note that any reference to a standard function such as:

    X = length( A )

causes the interpreter to scan to the end of the entire program searching for a possible user-defined function with the same name, which may be considerable overhead, whereas quoting the function name, as in:

    X = 'LENGTH'( A )

searches only for the standard (or possibly external) function.
