However, in order to be competitive with C in speed it would be useful
to be able to do the following:
For binary streams, declare the element-type of the stream, e.g. allow
the STREAM type specifier to take an optional element-type like ARRAY
I see no harm in this, if someone wants to propose it. I'm not sure
whether Symbolics would use it, but I think it's a reasonable thing
for imaginable implementations to want.
For binary streams, functions to read and write arrays in a single
chunk. Lucid supplies READ-ARRAY and WRITE-ARRAY as extensions.
For character input, a destructive version of READ-LINE.
Symbolics Genera has the equivalent of all of these under different
names. The read-array and write-array (shouldn't they be called
read-vector and write-vector?) are generic and work for character
streams as well, given a string as the vector. Someone should write
a proposal for these features. It might or might not be too late
to add this to X3J13 Common Lisp, but at least everybody could use
compatible names for their extensions.
