Well... maybe this then :)
vim is amazing, vim :help is galactic.
10. No +eval feature *no-eval-feature*
When the |+eval| feature was disabled at compile time, none of
the expression evaluation commands are available. To prevent
this from causing Vim scripts to generate all kinds of errors,
the ":if" and ":endif" commands are still recognized, though the
argument of the ":if" and everything between the ":if" and the
matching ":endif" is ignored. Nesting of ":if" blocks is
allowed, but only if the commands are at the start of the line.
The ":else" command is not recognized.
Example of how to avoid executing commands when the |+eval|
feature is missing:
:if 1
: echo "Expression evaluation is compiled in"
:else
: echo "You will _never_ see this message"
:endif

ok, I tried :set with the same result, FAIL.
I also put "set wrap" inside to see if it executed, it did not.
see T-5
I tried some not "expression-related" commands which FAIL.
see T-9 T-10
And tried some "expression-related" commands which do NOT fail.
Not only "expression-related", but are conditionals.
while ... endwhile
for ... endfor
try ... endtry
Seems only ":if" parsing is broken.
see T-2 T-8
T-6 is a strange case.
