• Proposal added
• Discussed in LDM 2018-09-10
• Decision in LDM
• Finalized (done, rejected, inactive)
• Draft spec in Draft spec for local function attributes #3008

The idea is to permit attributes to be part of the declaration of a local function.

From discussion in LDM today (4/29/2019), we would like to allow attributes on local function parameters, which would help with async-iterator local functions that want to use [EnumeratorCancellation].

Note: we did include support for extern as part of this work after all.
