Severity is 'minor' because there is a simple workaround.
D2 code:
int[3] foo;
void main() pure {
auto n = foo.length;
}
DMD 2.055 gives:
test.d(3): Error: pure function 'main' cannot access mutable static data 'foo'
But I think this code is correct because foo.length is a compile-time constant, so it doesn't break the purity of the main.
Workaround:
int[3] foo;
void main() pure {
auto n = typeof(foo).length;
}
