This is a mess, I have to agree.  The most important distinction is that
array() makes a copy of an array by default, while
inputarray()/asarray() does not.

Based on your input, and Tim Hochberg's earlier comments,  I think we
should:

1. Clean up the array function by ditching the buffer/sequence keyword
deprecation code.  buffer has been deprecated long enough.

2. Redefine asarray() as calling array() with copy=1.  Tim's right. 
It's a better name than inputarray() and we want it for backward
compatibility anyway.

3. Redefine inputarray() as a non-recommended synonym for asarray(). 
I'd say deprecate it,  but that's a PITA for anyone already using it.

4. Change the manual to document asarray() as primary and document
inputarray() as a non-recommended synonym.

Comments?
