OK, we remove Earl's comments.
Anyone could see that ESPL is not so simple than EL is.
Comments are added by me ( but was it necessary to tell it ?)

Comments, no, but ESPL code associated with "alternate replacement to EL",
yes!
"More difficut to use replacement", yes.
Do you remember that you are the maintainer of Omega List ( where most of
users are not C like programmers and have their own difficulties with
EL,however more simple than the above code. I do not copy the xaverage EL
code that is shorter, easier than the cleaned ESPL code above).
I have nothing against ESPL or whatever language you want.
I have a problem with false information that I can read on this list and
that nobody seems to want to fix excepted me...
And I am somewhat tired to be right all the time on this kind of topic ( ie
defending Omega products).
