A few of us hashed this out off-line, so I'm documenting the decision. I will submit a patch soon that adds modifiers for the character set semantics for the regex. That patch will only have them as infix, that is, in (?:...) clusters. They will be 'l', 'u', and 'd'. If these are to be also made suffix modifiers (/l, /u, /d) in 5.14, Jesse wants it enabled by a pragma to avoid any backwards compatibilty issues. They can be made suffixes in 5.16 without this pragma, as we are already deprecating the backwards compatibility issues in 5.14. Since I disagree with this decision, writing that pragma is low on my list of 5.14 priorities but anyone is certainly free to do so. But I don't think they will be used much as suffixes anyway, as they are automatically inserted: 'l' under 'use locale'; 'u' under 'use feature "unicode_strings"'; and 'd' otherwise. I don't see much need to over-ride these on an individual regex basis, so don't see much need for the suffix modifiers.Thread Previous | Thread Next
