Suggested correction to explanatory text for exercise 14

[SRNissen]

The current text is technically false. As of today, it is written:

// Problem:
// For statements can also have init and post statements in the clause.
//
//  for i := 0; i <= 10; i = i + 1 {
//      fmt.Println(i)
//  }
//
// The above for loop will iterate from 0 to 10 and is
// identical in functionality to the following
// single-condition for statement:
//
//  i := 0
//  for i <= 10 {
//      fmt.Println(i)
//      i = i + 1
//  }

which would leave i in scope after the loop block, which is true in some languages but not here.

Proposed change

The exercise text could instead be

// Problem:
// For statements can also have init and post statements in the clause.
//
//  for i := 0; i <= 10; i = i + 1 {
//      fmt.Println(i)
//  }
//
// The above for loop will iterate from 0 to 10 and is
// identical in functionality to the following
// single-condition for statement:
//
// {
//      i := 0
//      for i <= 10 {
//          fmt.Println(i)
//          i = i + 1
// }

I'm a bit on the fence with the idea of adding anonymous scopes as that is a feature that may catch some off guard. Maybe we can change the comment:

// The above for loop will iterate from 0 to 10.
// The following single-condition for statement
// will also perform the same operations:

This sound good?
