Summary: Allow atomic types in typeof() or improve error message
Product: D
Version: 2.009
Platform: PC
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: DMD
AssignedTo: bugzilla at digitalmars.com
ReportedBy: aarti at interia.pl
Currently first assert compiles, but the second one not:
void main() {
class A {}
static assert(is( typeof(new A) == typeof(A)) ); // 1
static assert(is( typeof(new int*) == typeof(int*) )); // 2
}
I propose for consistancy to:
1. Allow typeof to take also atomic types.
2. Improve error message when compiler fails. Currently:
quicktest.d(62): found '*' when expecting '.' following 'int'
quicktest.d(62): found ')' when expecting identifier following 'int.'
quicktest.d(62): found ';' when expecting ')'
quicktest.d(64): found '}' when expecting ';'
quicktest.d(65): found 'EOF' instead of statement
quicktest.d(65): found 'EOF' instead of statement
quicktest.d(65): found 'EOF' instead of statement
