First of all, what does this mean? Secondly, just because the answer to something is false, doesn’t mean it’s unreasonable to ask the question.
Please show an actual piece of code that you think is a footgun.
I am going to guess that it’s this:
julia> issorted([1, 1], lt = <=)
false
And the footgun is that a user expects that it returns true? The user will have to have read the docstring for issorted to even know the keyword argument is called lt:
Test whether a vector is in sorted order. The lt, by and rev keywords modify what order is considered to be sorted just as they do for sort.
So, after reading that, the user passes in lt = <=. What is the logical or emotional justification for a user doing that?
