Martin Atkins ae3c0c6a4a lang/funcs: Remove the deprecated "list" and "map" functions ... Prior to Terraform 0.12 these two functions were the only way to construct literal lists and maps (respectively) in HIL expressions. Terraform 0.12, by switching to HCL 2, introduced first-class syntax for constructing tuple and object values, which can then be converted into list and map values using the tolist and tomap type conversion functions. We marked both of these functions as deprecated in the Terraform v0.12 release and have since then mentioned in the docs that they will be removed in a future Terraform version. The "terraform 0.12upgrade" tool from Terraform v0.12 also included a rule to automatically rewrite uses of these functions into equivalent new syntax. The main motivation for removing these now is just to get this change made prior to Terraform 1.0. as we'll be doing with various other deprecations. However, a specific reason for these two functions in particular is that their existence is what caused us to invent the idea of a "type expression" as a distinct kind of expression in Terraform v0.12, and so removing them now would allow potentially unifying type expressions with value expressions in a future release. We do not have any current specific plans to make that change, but one potential motivation for doing so would be to take another attempt at a generalized "convert" function which takes a type as one of its arguments. Our previous attempt to implement such a function was foiled by the fact that Terraform's expression validator doesn't have any way to know to treat one argument of a particular function as special, and so it was generating incorrect error messages. We won't necessarily do that, but having these "list" and "map" functions out of the way leaves the option open.		2020-11-04 17:05:59 -08:00
