P.S.: we are of course in the field of things which are beyond
standard definitions.  And there _are_ bugs in the bash evaluator,
on the same precedence level as i have shown:

  $ bash -c ' I1=I2=10 I2=5 I3=I2+=1; echo "<$(( I1*=1?I1:I3 ))>";echo "<$I1><$I2><$I3>"'
  <100>
  <100><10><I2+=1>
  $ bash -c ' I1=I2=10 I2=5 I3=I2+=1; echo "<$(( I1=1?I1:I3 ))>";echo "<$I1><$I2><$I3>"'
  <10>
  <10><10><I2+=1>

  ...
 |Now, this is ridiculous.  I am sorry for that.

Sigh!!
