[issue41392] SyntaxError rather than NameError

[Eric V. Smith]

Eric V. Smith  added the comment:

As an example of why it's not possible for the compiler to treat this as a 
syntax error: I use python for my config files. Before I load these files, I 
inject names into the builtins, so that the config files can reference them. 
Some of these are constants, others are callbacks. "false" or anything else 
could be one of the injected names.

[issue41392] SyntaxError rather than NameError

[Ronald Oussoren]

Ronald Oussoren  added the comment:

The compiler cannot know if "false" is an existing name when compiling. 

One example is that the name might refer to the name of a builtin.

[issue41392] SyntaxError rather than NameError error

[wyz23x2]

wyz23x2  added the comment:

There is nothing *wrong* with the syntax; it's just a regular assignment.
It's not something like `False = 4` or `while = 6` which '=' is invalid.
