[ cites various front ends ]

Certainly; but bear in mind that all these front ends use the "pty" driver,
which is a bletcherous hack*, kludged in to get around the problems that
cooked mode causes.  I should be able to fake normal keyboard input with a
simple pipe.

When you use, e.g. "fep", you are using "readline" anyway.  You're just
sending the result through an extra device driver to fake cooked mode.

More efficient?  I think not.

The ideal solution would be a reasonably-standard, dynamically linkable
input library, so you could link to whatever interface you preferred.

Exactly.

*: I am NOT criticizing the implementation or the design of the pty driver.
In fact, I consider pty a necessity.  I am criticizing the obsolete design
which makes it a necessity.
