I think I discovered a bug in ksh.
works with all shells, including ksh in normal mode.
But does not work with ksh -x: sh -x or bash -x or zsh -x do it correctly:
I guess I don't see what's wrong.
It looks like ksh is running the parts of the pipelines in different threads (so you see jumbled output in the trace), but both x and y are assigned empty values and the echo $x and echo $y seem to have done the right thing. What am I missing?
If you mean that the trace output from bash and zsh don't show redirection operations performed by the shell, I don't think that is a ksh bug.

define
DEFINE(3) 1 DEFINE(3)define - Defines a named constantSYNOPSIS
bool define (string $name, mixed $value, [bool $case_insensitive = false])
DESCRIPTION
Defines a named constant at runtime.
PARAMETERS
o $name
- The name of the constant.
o $value
- The value of the constant; only scalar and null values are allowed. As of PHP 7 it also possible to use array value. Scalar val-
ues are integer, float, string or boolean values. It is possible to define resource constants, however it is not recommended and
may cause unpredictable behavior.
o $case_insensitive
- If set to TRUE, the constant will be defined case-insensitive. The default behavior is case-sensitive; i.e. CONSTANT and Con-
stant represent different values.
Note
Case-insensitive constants are stored as lower-case.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
