Evaluate Perl expression {expr} in scalar context and return its result converted to Vim data structures. If value can't be converted, it is returned as a string Perl representation. Note: If you want an array or hash, {expr} must return a reference to it. Example: :echo perleval('[1 .. 4]') [1, 2, 3, 4] Note that in a :def function local variables are not visible to {expr}. Can also be used as a |method|: GetExpr()->perleval() {only available when compiled with the |+perl| feature}
