Declare a function where it belongs, or onto a table.

Warning

Worth knowing before you upgrade.

0.24.0On Table has to resolve to a name — a variable or a local. Luau has no syntax for attaching a function to an expression, so anything else is refused rather than half-written.
0.24.0The function is named where it is declared, so a Get Function above it reports that it does not exist yet rather than naming a local that has not been reached.

0.24.0Declare Function, which declares a function where the node sits rather than at the top — the other half of Function, the way Declare Type is the other half of Declare Type at Top. Wire a table into On Table and it becomes function TankConfig.read(tank: Model): Config; leave it unwired for a plain local function at that point in the flow.

0.24.3A Declare Function gets a blank line either side, the same as a hoisted one. Two run together read as a single block with an end somewhere in the middle of it.
0.24.2A graph with only Declare Function nodes compiles. Every Get Function was reported as pointing at a function no longer in the graph, because the check only counted the hoisted node.
0.24.2Declare Function can be chosen in a Get Function. The dropdown listed it, took the click and discarded it, so the selection snapped back with nothing said.
0.24.2Renaming one updates the references to it, and it now appears in the palette as Get <name> and in hand-written Luau completions.
0.24.1A Declare Function node's function can be wired into a call. Its Function output was reported as out of scope, because passing a function as a value was special-cased to the hoisted node.
0.24.1Its header reads Declare Function (name), with the signature underneath, instead of replacing the node's name with the function's.
