- !ruby/struct:SM::Flow::P
body: Evaluates a string containing Ruby source code, or the given block, within the context of the receiver (<em>obj</em>). In order to set the context, the variable <tt>self</tt> is set to <em>obj</em> while the code is executing, giving the code access to <em>obj</em>'s instance variables. In the version of <tt>instance_eval</tt> that takes a <tt>String</tt>, the optional second and third parameters supply a filename and starting line number that are used when reporting compilation errors.
