Dear Marek,

I think =+ will confuse far more people than + as last character of var
I still fail to see why '=+' could be confusing if properly documented to be the append operator.
I mean, it is not a new invention of mine.
OpenEmbedded / Yocto uses '=+' a lot, like in
meta/recipes-kernel/dtc/dtc.inc:
PACKAGES =+ "${PN}-misc"
Actually they use both '+=' and '=+', like
RESULT+=${ERRORS}
The OE example is exactly why I want to avoid =+. You cannot interchangeably use += and =+ as they evaluate differently. See https://www.yoctoproject.org/docs/3.1/bitbake-user-manual/bitbake-user-manua... and that =+ there is the opposite of what we want. So, more confusion.
