Previously, inline condition only replicates on its condition. For example, for the following code,\r\n```\r\nx = {1, 2, 3};\r\ny = {4, 5, 6};\r\nz = {7, 8, 9};\r\nr = x > 1 ? y : z;\r\n```\r\nPreviously `r = x > 1 ? y : z` only replicates on condition `x > 1`, therefore `r` is `{z, y, y}`, that is `{{7, 8, 9}, {4, 5, 6}, {4, 5, 6}}`. Now as it replicates on all three branches, `r` is `{7, 5, 6}`:\r\n```\r\n{1>1  2>1  3>1}\r\n  ?    ?    ?\r\n{ 4    5    6}\r\n  :    :    :\r\n{ 7    8    9}\r\n```\r\nEvaluating both true and false branches might have unexpected result in some cases (but it wouldn't be a problem in Dynamo because Dynamo will evaluate each node that put on the canvas immediately in Run Automatically mode):\r\n  * Recursive function doesn't work in inline condition, it will cause an infinite loop. For example:\r\n```\r\n    def fact(x)\r\n    {\r\n        return x > 1 ? x * fact(x - 1) : 1;  // infinite loop\r\n    }\r\n```\r\n  * Global value may be changed in unexpected way\r\n```\r\n    a = 0;\r\n    def update_a() \r\n    {\r\n        a = a + 1; \r\n        return = a;\r\n    }\r\n    r = false ? update_a() : update_a();    // r = 2, a = 2;\r\n```\r\n### Declarations\r\n\r\n- [ ] The code base is in a better state after this PR\r\n- [ ] The level of testing this PR includes is appropriate\r\n\r\n### Reviewers\r\n\r\n- [ ] @lukechurch \r\n\r\n- [ ] @junmendoza \r\n\r\n### FYIs\r\n\r\n@kronz , @mccrone As `IF` node is compiled to inline condition, its output will be changed.
