Think about the following a little before doing a knee-jerk "No".
What if we put in a kludge so that it remained fatal except when
compiling the exact single pattern that autoconf uses? It is
/\${[^\}]*}/
Thus, when we are about to die, we check if the pattern attempting to be
compiled is this exact one, and if so, merely warn.
It is the one way I can think of that keeps us from being held hostage
to this lackadaisical alien project for who knows how many more Decembers.
What are the downsides?
1. It is inelegant
2. It is inelegant
3. It is inelegant
...
n-1. It is inelegant
n. Any other code that has this exact pattern would compile instead of
not. But so what? This particular pattern would not be affected by any
of the proposed changes that making this illegal would allow. They are,
so far,
a. to be able to say \w{something}
b. to be able to have white space and a missing lower bound in {...}
quantifiers.
