Summary: cannot access string member in const method
Product: D
Version: 2.006
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: bugzilla digitalmars.com
ReportedBy: i.kasiuk gmx.de
Maybe I just don't understand const and invariant properly. But I wonder why
the following code doesn't compile:
class A {
string s;
const string f() { return s; }
}
The error message is:
test.d(3): Error: cannot implicitly convert expression (this.s) of type const
char[] to invariant(char)[]
Why does it state that s is of type const char[]? Shouldn't it be const
invariant(char)[]?
Replacing "return s;" by "return cast(string) s;" fixes the compilation error.
But why do I have to cast s to its own type?
The compilation error also disappears if the method is invariant instead of
const.
