[CMake] what is wrong with this snippet? (bug?)
set(!BANG wacky CACHE STRING "" FORCE)
set("var with space" wacky CACHE STRING "" FORCE)
message(STATUS "This is !BANG: ${!BANG}")
message(STATUS "This is var with space: ${var with space}")
The above snippet (as expected) causes a CMake error. What's interesting
is that the error is in the message, not the set. More so, the variables
do indeed end up in the cache!
The utility of a variable that can't be referenced seems... dubious.
Should CMake prevent this?
(cmake 2.6-2)

Please create a bug entry. Also, don't create variables with odd
characters in them as CMake does not correctly warn that this is invalid
right now. :)

Done [1], and thanks. I wasn't sure how this was supposed to work.

No worries, I was actually hoping the set would fail also. As mentioned
in [2] I was trying to work around bug 8226 [3], and wanted to verify
that such variables were invalid. So, I hope they will stay invalid ;-).
(But yes, it would be good for SET to fail, as well as expansion.)
