a bit of my opinion:
I think =+ will confuse far more people than + as last character of var
name working weirdly. But I also think that + should be supported as
last character. Therefore I propose backslash escaping in variable name,
i.e.
  var+=value
appends value to var, while
  var\+=value
sets variable with name "var+"
