Let's say you have this as a lambda:
int a = ...;
auto lambda = [x(int(a))]{ return x + 1 };
An
init-capture inhabits
the lambda scope ([basic.
scope.
lambda])
of the
lambda-expression.An init-capture without ellipsis
behaves as if it declares and explicitly captures a variable of
the form “auto init-capture ;”, except that (...omitted...)
The "auto init-capture ;" part seems wrong here, because the lambda above would fall to the most vexing parse rule:
auto x(int(a)); // declares a function, not an int
I guess this could be an editorial-level issue? Clearly the Standard's intent is that x would be interpreted as an int here, rather than be a very weird application of the most vexing parse rule...?
