I’ve seen a few examples where one can use a bare underscore in an expression, e.g., julia> map(_ -> "hello", 1:4) 4-element Array{String,1}: "hello" "hello" "hello" "hello" julia> ["hello" for _ in 1:4] 4-element Array{String,1}: "hello" "hello" "hello" "hello" julia> for _ in 1:4 …

Usage rules for bare underscores
