Ask HN: I casually came up with chained unary operators, do you like them?

Working on a simple virtual machine and a new programming language, I have discovered that the interpreter I have developed can read chained unary operators nominally.

It seems a useful side effect...

$a = 0

print ++$a++

# Prints "1" and sets a = 2 in memory

$a = 1

print --$a++

# Prints "0" and sets a = 1 in memory

$a = 0

print ++++$a

# Prints "2" and sets a = 2 in memory

$a = 0

print $a++++

# Prints "0" and sets a = 2 in memory

$a = 10

print ++$a----

# Prints "11" and sets a = 9 in memory

$a = 10

print ++--$a----++

# Prints "10" and sets a = 9 in memory
