Hi,
Mauricio, sorry for hijacking your thread. : )
I have one question about handling or parsing decimal places. I
noticed that Haskell doesn't accept values starting with just the
point, e.g., .50 or .01. I suppose that's abuse of notation in the
first place (and I'm guilty of it), but I ofte
Agree about the answer, not about the question. The
correct one would be "is it possible to change haskell
syntax to support the international notation (...)
For some sense of "possible", the answer is clearly yes.
However, it is perhaps misleading to call commas
"THE international notation". (

No! If we had that, string from a program would not

Do you think 'read' (actually,
'readsPrec'?) could be made to also

(ie., read "1,5" would also work
besides read "1.5")?
No, as read is really intended to be a language-level tool, not
something that you should expose to end users. For local
Given examples like (1,2,3) I don't see how comma could ever be used
instead of dot, unless you insist on whitespace around all commas.
And that doesn't look like the right way forward.

Really?
There is a bunch of languages (like "Glagol") that use words of Russian
language as keywords; AFAIK there aren't any Russian programmer who uses
them
Maybe. Doubles 'show' function always print something
after the decimal separator, so 'show [doubles]' is
easy to parse but difficult for human reading. It
would be nice to have a space between elements of a
shown list, though. It's an annoyance, but
internationalization is really great, I think i
No, it is not. Strings created by show are
always supposed to be readable by read, no
matter which system used 'show' and which
system is using 'read'.
