We have merged the parsers into one, because we had 3 parsers that didnât have any dedicated use-cases, juts were developed historical as at some point someone needed a bit more functionality, and then different parsers were used randomly on the system.
Yes, it was quite hard to understand what was going on. And it is strange to have 3 different parsers for numbers...
As for the expression - yes we have to decide about it. If itâs only about being able to use exponent in float literals, one can use: âNumber readFrom: '2.5850009999999998e04ââ. If itâs about being similar to the other languages, we can also decide does it make sense to have a +2 literal.
If it makes no problems with backward compatibility, why not have both?

I personally would prefer to be able to use exponents. No sure what the big picture is. cheers -ben Of course exponents are still supported ;-)
The discussion is about the + sign for positive exponents. I am not sure, but I think that traditional Smalltalk did not support this, but it was added to support common practice in other languages. Now it is apparently gone again, probably not on purpose.
I do not know I think that marcus removed it to avoid to have two parsers in the image.
Maybe this was a mistakeâ¦
