If any - exist, they are bugs and reports are welcome. +Acceptable version number formats have been formalized into "strict" and +"lax" rules. C takes a strict version number. C takes a lax version number. C and the +L object constructors take lax version numbers. Providing an +invalid version will result in a fatal error. +These formats will be documented fully in the L module in a +subsequent release of Perl 5.11. To a first approximation, a "strict" +version number is a positive decimal number (integer or decimal-fraction) +without exponentiation or else a dotted-decimal v-string with a leading 'v' +character and at least three components. A "lax" version number allows +v-strings with fewer than three components or without a leading 'v'. Under +"lax" rules, both decimal and dotted-decimal versions may have a trailing +"alpha" component separated by an underscore character after a fractional +or dotted-decimal component. -=head1 Core Enhancements +The L module adds C and C +functions to check a scalar against these rules. -XXX New core language features go here.
