int foo(int n, int m)
{
    int x = foo( 5, m;
    for (int q=0; q<10; ++q){
       ++q;
    }
    return  2;
}

The error is a single missing ')'. But the compiler spits an error for each
extra token in the file. Probably, as soon as it hits an unexpected ;, it
should assume that it has reached the end of the argument list.
In reality this situation often happens in situations where the last parameter
is a function call, and parentheses are mismatched:
foo(5, foo(3, foo(7,6));

Some cases that look related (but I don't know if they are actually similar).

From the thread: http://forum.dlang.org/thread/osnevnwnshreoaudleep@forum.dlang.org

In the following examples I'd like the D compiler to give more focused error messages.

----------------------

int main() {
     for (int i = 0, i < 10, i++) {
         // do something
     }
     return 0;
}


temp.d(2): Error: semicolon expected, not '<'
temp.d(2): Error: expression expected, not '<'
temp.d(2): Error: found '10' when expecting ';' following for condition
temp.d(2): Error: expression expected, not ','
temp.d(2): Error: found 'i' when expecting ')'
temp.d(2): Error: expression expected, not ')'
temp.d(2): Error: found '{' when expecting ';' following statement
temp.d(5): Error: Declaration expected, not 'return'
temp.d(6): Error: unrecognized declaration

----------------------

void main() {
     foreach (i, 0 .. 10) {}
}


temp.d(2): Error: basic type expected, not 0
temp.d(2): Error: no identifier for declarator int
temp.d(2): Error: found '0' when expecting ';'
temp.d(2): Error: expression expected, not '..'
temp.d(2): Error: found '10' when expecting ')'
temp.d(2): Error: found ')' instead of statement
temp.d(3): Error: unrecognized declaration

---------------------------------

void main() {
     int[10] data;
     foreach (i, x, data) {}
}



temp.d(3): Error: no identifier for declarator data
temp.d(3): Error: found ')' when expecting ';'
temp.d(4): Error: found '}' when expecting ')'
temp.d(4): Error: found 'EOF' instead of statement
temp.d(4): Error: found 'EOF' when expecting '}' following compound statement

---------------------------------

void main() {
     int[10] data;
     foreach (i; x; data) {}
}


temp.d(3): Error: found ';' when expecting ')'
temp.d(3): Error: found ')' when expecting ';' following statement

---------------------------------

void main() {
   int value = 0;

   while (value < 10) do {
     // do something
     value++;
   }
}
