libsyntax-operator-is-perl

Description

Syntax::Operator::Is provides an infix operator that checks if a given value matches a value constraint provided by Data::Checks.

Support for custom infix operators was added in the Perl 5.37.x development cycle and is available from development release v5.37.7 onwards, and therefore in Perl v5.38 onwards. The documentation of XS::Parse::Infix describes the situation in more detail.

While Perl versions before this do not support custom infix operators, they can still be used via XS::Parse::Infix and hence XS::Parse::Keyword. Custom keywords which attempt to parse operator syntax may be able to use these. One such module is Syntax::Keyword::Match.
