Call to previously defined function (and macro?) by name prefixed with '_' is not documented
In his cppnow presentation Effective CMake Daniel Pfeifer states
When a new command replaces an existing command, the old one can be accessed with a
_
prefix.
I have not found any trace of this in the documentation of function
, macro
and in cmake-language
.
Is this behavior correctly described and if yes, where should it be added to the documentation?
