text/template/parse

Hi, wanted to create wrapper for the standard text/template/parse/library but the generated code contains following:

```python
if 3 < len(args):
self.True = args[3]
```
where
```python

@property
def True(self):
return _htoy.parse_BoolNode_True_Get(self.handle)
```

which obviously leads to the following python error:

```
byte-compiling build/bdist.macosx-14-x86_64/egg/htoy/go.py to go.cpython-311.pyc
byte-compiling build/bdist.macosx-14-x86_64/egg/htoy/parse.py to parse.cpython-311.pyc
File "build/bdist.macosx-14-x86_64/egg/htoy/parse.py", line 1490
self.True = args[3]
```
Thanks for considering this and hope it helps to improve your wonderful work

从为 Go 的 text/template/parse 包生成的 wrapper 开始，尤其检查生成的 parse.py 代码中所报告的 self.True 赋值和属性附近的部分。重现 build 和字节编译失败，然后验证生成的模块能够在不包含无效 Python 标识符的情况下成功编译。
