class

Myst::Call

Inherits Myst::Node / Reference / Object

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 ] | expression '(' [ arg [ ',' arg ]* ] ')' [ block ] | arg operator arg

Any expression can be forced into a Call by adding parentheses as a suffix. Complex expressions will require parentheses around the expression to avoid ambiguity. This is the third form shown above.

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

Constructors
