| 59 | <P> |
| 60 | There are some problems with the error checking of the compiler |
| 61 | package. The interpreter detects syntax errors in two distinct |
| 62 | phases. One set of errors is detected by the interpreter's parser, |
| 63 | the other set by the compiler. The compiler package relies on the |
| 64 | interpreter's parser, so it get the first phases of error checking for |
| 65 | free. It implements the second phase itself, and that implementation is |
| 66 | incomplete. For example, the compiler package does not raise an error |
| 67 | if a name appears more than once in an argument list: |
| 68 | <code>def f(x, x): ...</code> |
| 69 | |
| 70 | <P> |
| 71 | A future version of the compiler should fix these problems. |
