And also many lines of Matlab/Octave code in experimental science.
Surprisingly enough, it seems that Matlab does not support AE, but GNU 
Octave does.
I don't know if that was ever discussed when GNU Octave was designed.

octave:1> y=(x=2)+1
y =  3
octave:2> x
x =  2

versus Matlab R2018b:
 >> y=(x=2)+1
  y=(x=2)+1

Error: Incorrect use of '=' operator. To assign a
value to a variable, use '='. To compare values for
equality, use '=='.
