Bug 8249 – Spurious error message with templates and alias this

Seems like a lookup is not attempted if an error has previously occurred in the module. This example comes from template9.d, and was based on bug 7580. -------- void deliberateError() { int someError = "abc"; } void fred()(int value) {} struct YY { int val; @property int get()() { return val; } alias get this; } void test() { YY y; fred(y); } bug.d(1): Error: cannot implicitly convert expression ("abc") of type string to int bug.d(3): Error: template junk.fred() cannot deduce template function from argument types !()(YY) The second error disappears if the first line is commented out.
