There is one situation I have encountered where it would be useful to
have a built in [arraysize]. In some of the s-abstractions such as
[s-samplepiece~] you have to pass in the table name that you'd like the
abstraction to use. This means that at some point the user loads some
audio data into the named table (for example using [s-loader~]) and they
then know the sample table size. When they create the [s-samplepiece~]
playback abstraction they must manually enter the array size as one of
the arguments to the abstraction, along with the table name.
