JLFunction does not support x -> x

[josephmckinsey]

Using [6b7a57c9] Expronicon v0.10.3 on Julia 1.9.0, JLFunction cannot construct a function from an anonymous function with only one input. Somewhat strangely, JLFunction(:((x, y) -> x)) does work.

julia> using Expronicon

julia> JLFunction(:(x -> x))
ERROR: MethodError: no method matching split_function_head(::Symbol; source::Nothing)

Closest candidates are:
  split_function_head(::Expr; source)
   @ Expronicon ~/.julia/packages/Expronicon/7EBrJ/src/analysis/split.jl:43

Stacktrace:
 [1] JLFunction(ex::Expr; source::Nothing)
   @ Expronicon ~/.julia/packages/Expronicon/7EBrJ/src/analysis/cons.jl:30
 [2] JLFunction(ex::Expr)
   @ Expronicon ~/.julia/packages/Expronicon/7EBrJ/src/analysis/cons.jl:16
 [3] top-level scope
   @ REPL[2]:1

This probably just needs split_function_head to have a new case for symbol, maybe.

Oh, this was fixed by #71

Cool. Nice to see the case ::Int -> 0 I didn't even know about covered.
