   ++ BEGINFILE ii.x7yz.1

i code shortened coding codings, or at least wish to
here in my x7yz control script i '. -- +al' a ./+al file which then
sets aliases by file content, it does so
but the resulting +al alias of itself says when usage syntax error ';'
unexpected
some other aliases work tho

any ideas ?
