So now the user must make sure to balance this new quote? Or use @&t@ or
something to break it up? I'm afraid I'm never going to remember this.
That opening quote looks like an operator, -=, followed by the start of
some special grouping construct, <{, followed by an opening parenthesis.
I'd hate to be the poor developer of an experimental language containing
such a grouping construct and then try to write a test case with:
AT_SETUP([[Scanner Test: a-=<{(1+b)*5}>]])
Or maybe just a regexp engine test with a character class containing
operators accidentally in the above order:
AT_SETUP([[Regexp Test: [-=<{()}>!+]]])
I find it rarely pays to play the guessing game of "surely the user will
never do *this*". Moreover, I'm betting that the user will never guess
that this bizarre string is actually special to autotest. At the very
least, can this new limitation be mentioned in the manual? Or did I miss
it?
Thanks.
