We can define that backslash is to be also escaped if it is to be used as variable name: weird_var\\\+=abcd I still think it is far more intuitive than =+. Anyway, IMO '+' as the last character in varname is a extreme corner case; I think that no one sane actually uses it. But even if they did, Simon's patches do not break it. Simon's patches only disallow it in board environment definition during compilation. I think it is a completely reasonable thing to diallow board maintainers (i.e. only U-Boot developers, not users) from using such construction. Marek
