I"DReturns an indication of the number of arguments accepted by a ;TI"Imethod. Returns a nonnegative integer for methods that take a fixed ;TI"Jnumber of arguments. For Ruby methods that take a variable number of ;TI"Karguments, returns -n-1, where n is the number of required arguments. ;TI"KKeyword arguments will be considered as a single additional argument, ;TI"Ithat argument being mandatory if any keyword argument is mandatory. ;TI">For methods written in C, returns -1 if the call takes a ;TI""variable number of arguments.;To:RDoc::Markup::BlankLineo:RDoc::Markup::Verbatim;	[!I"
