Yes, I agree with this. I have gotten in the habit of always
writing TOTAL(/NAN), but it would be nice if this were the
default.
A vaguely related wish of mine is that compile_opt idl2 finally be
made the default. I appreciate that ITTVIS wants to have backward
compatibility, but square brackets were introduced 11 years ago, and
do we still need default 16 bit integers? If there is anyone who
still wants their 11 year old software packages to run without
modification, ITTVIS could add a compile_opt idl1 (or compile_opt
idl_ancient) command.
