Issue ID: 17703
Summary: __traits(compiles, AssignmentExpression) no longer
compiles without surrounding parens
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: regression
Priority: P1
Component: dmd

void Test(T...)()
{
static assert(__traits(compiles, T[0] = T[1]), "Doesn't compile");
}
void main()
{
int x;
int y;
Test!(x, y)();
}
This code fails to compile with:
(3): Error: found '=' when expecting ')' following template argument list
(3): Error: found 'T' when expecting ')'
(3): Error: found '[' when expecting ';'
(3): Error: found ']' when expecting ';' following statement
(3): Error: found ')' instead of statement
It used to compile a few years ago.
Enclosing `T[0] = T[1]` in parentheses will allow it to compile.
void Test(T...)()
{
static assert(__traits(compiles, (T[0] = T[1])), "Doesn't compile");
}
void main()
{
int x;
int y;
Test!(x, y)();
}
