Proposal Link: swift-evolution/0053-remove-let-from-function-parameters.md at master · apple/swift-evolution · GitHub
The review of SE-0053 "Remove explicit use of let from Function Parameters" ran from Mar 24…27, 2016. The proposal has been *accepted*:
Everyone agrees that including this redundant syntax is pointless given that the var/inout syntax has been removed or moved, it probably should have been included with SE-0003.
Thank you to Nicholas Maccharoli for driving this forward, and thanks to Manav Gabhawala who is working on an implementation of this, in PR1812!
