Bug 13051 – Cannot use function literal inside struct initializer

It appears that function literals cannot be used within struct initializers. It seems to result in a syntax error if then function literal contains any code. I've provided the following code to demonstrate the issue. void main() { struct UseConstructor { void function() fp; this(void function() fp) { this.fp = fp; } } // Compiles fine UseConstructor s1 = UseConstructor((){int a = 1;a += 24;}); struct UseInitializer { void function() fp; } // Compiles fine void function() fp1 = (){int a = 1;a = a * 7;}; UseInitializer s2 = {fp:fp1}; // Compiles fine UseInitializer fs3 = {fp:(){}}; // Fails UseInitializer fs4 = {fp:(){int a = 1;}}; // It seems that the code inside the function literal is causing a syntax error } The error messages from compilation appear as: Error: found '}' when expecting ';' following statement Error: semicolon expected, not 'EOF' Error: found 'EOF' when expecting '}' following compound statement

Tested the code in the bug report. It compiles fine.

Thanks for checking Nathan. I just tried this as well, works on dmd 2.082, but not 2.079, so something must have come in between those 2 version to fix this.
