Hello, guys.<br>
<br>
Python has more and more reserved words over time. It becomes quite annoying, since you can not use variables and attributes of such names. Suppose I want to make an XML parser that reads a document and returns an object with attributes corresponding to XML element attributes:<br>
<br>
> elem = parse_xml("<element param='boo'/>")<br>
> print elem.param<br>
boo<br>
<br>
What should I do then, when the attribute is a reserver word? I could use trailing underscore, but this is quite ugly and introduces ambiguity.<br>
<br>
> elem = parse_xml("<element for='each'/>")<br>
> print elem.for_ #?????<br>
> elem = parse_xml("<element for_='each'/>")<br>
> print elem.for__ #?????<br>
<br>
My proposal: let's make a syntax change.<br>
<br>
Let all reserved words be preceded with some symbol, i.e. "!" (exclamation mark). This goes also for standard library global identifiers.<br>
<br>
!for boo in foo:<br>
!if boo is !None:<br>
!print(hoo)<br>
!else:<br>
!return !sorted(woo)<br>
<br>
<br>
This would allow the user to declare any identifier with any name:<br>
<br>
for = with(return) + try<br>
<br>
What do you think of it? It is a major change, but I think Python needs it.<br><font color="#888888">
