class Myst::Call

Overview

A method call. Calls are the building block of functionality. Any operation not expressed by a distinct node is considered a call. For example, a + b is a call to the method + on a with b as an argument, obj.member is a call to the method member on obj, etc. Additionally, any identifier that is not known to be a local variable (created by a SimpleAssign or MatchAssign) is considered a Call.

[ receiver '.' ] name [ block ] | [ receiver '.' ] name '(' [ arg [ ',' arg ]* ] ')' [ block ] | arg operator arg

The last form is for infix operations, such as a + b shown above, where operator would be the +.
