我想查看REPL中方法的定义。我关注此链接(https://github.com/JuliaLang/julia/issues/2625),但它不起作用:
julia> f(x) = x^2
f (generic function with 1 method)
julia> expand(f)
f (generic function with 1 method)
julia> methods(f)
# 1 method for generic function "f":
f(x) at REPL[155]:1
julia> implementation(f,1)
ERROR: UndefVarError: implementation not defined
in eval_user_input(::Any, ::Base.REPL.REPLBackend) at ./REPL.jl:64
in macro expansion at ./REPL.jl:95 [inlined]
in (::Base.REPL.##3#4{Base.REPL.REPLBackend})() at ./event.jl:68
似乎方法implementation
不存在。
