@framasky @Sasha Yes, but Perl (unlike Prolog or Go) has no constraint on the case of the identifiers so it is not a problem. The case (pun intended) is interesting because Prolog requires a specific case.

@framasky @bortzmeyer @Sasha does it accept whitespaces (like U+a0) as identifiers as well? 😁

@mmu_man @bortzmeyer @Sasha nope. Not even non breaking spaces 🙁

@framasky Once again, discrimination against my favourite char (Non breaking zero witdh space).

@mmu_man @bortzmeyer @Sasha

@ffeth @mmu_man @bortzmeyer @Sasha Poor \uFEFF 🙁 I like it too.

@framasky @ffeth @bortzmeyer @Sasha BOM? BOF...

@framasky @ffeth @mmu_man @Sasha Non-breaking space is now U+2060, I believe.

@bortzmeyer @framasky @ffeth @Sasha U+2060 WORD JOINER ?
Didn't know this one.
U+00A0 NO-BREAK SPACE is not 0-width anyway.

@mmu_man @framasky @ffeth @Sasha U+2060 is intended to replace U+FEFF as a non-breaking zero-width space, leaving U+FEFF as BOM and BOM only.

@bortzmeyer @mmu_man @framasky @ffeth Wow, it's so weird to find a whole solid conversation when you come home a bit late and to wonder why you're included in it and… nooo I never went further in Prolog than some initiation during the MPRI and… I don't know Cherokee ?! So I think it's a very interesting problem but I don't feel very qualified to discuss it. Sorry : )

@ffeth @framasky @bortzmeyer @Sasha well it's not a question of width.
