+## For Loops
 
+Allow C/C++ style `for` loops:
+
+`for( init; test; next ) body`
+
+```cpp
+int sum=0;
+for( int i=0; i<arg; i++ )
+    sum = sum + i;
+return sum;
+```
+
+Any of `init`, `test` and `next` can be empty.
+`init` allows for declaration of a new variable, with scope limited to the `for` expression.
+
+```cpp
+int sum=0;
+for( int i=0; i<arg; i++ )
+    sum = sum + i;
+return sum;
