Defined in:

Overview

Replaces a method-call argument with its receiver: ‘fn(x.attr)` -> `fn(x)`. High-signal for log payloads, structured-data construction, and API request bodies where a method call on a local variable / param appears in argument position. Covered byte-wise by `MethodCallRemoval` already; this operator surfaces the same byte change under a more specific name so the argument-substitution pattern is legible in mutation output.

Fires for:

  • positional / keyword arguments of any CallNode

  • hash values inside HashNode / KeywordHashNode (incl. inside call args)

  • array elements inside ArrayNode
