Thanks for the patch!
A [version based on your patch, along with a unit test has been
committed to trunk][r13508].
And I've [opened up a new ticket to track porting named-readtables
to abcl][#161], at which I have looked briefly. The named-readtable
tests claim to succeed. The main part for porting would be to
implement a readtable iterator, although there is a supposedly
portable implementation that should work on a ANSI CL. It seems
that the parenscript use of named-readtable starts using a readtable
that should invert case but the merge from the standard namespace
then attempts to use this inversion on symbols like 'SYSTEM by
trying for 'system instead. I am unsure of how much work it will
take to disentangle the cause here, but I've run out of free time
for today.
