Defining a function named "parse" fails in peculiar circumstances

[dcjones]

This is JuliaLang/JuliaParser.jl#18. Posting here because it's pretty clearly a julia bug.

This is as minimal a test case as I could find:

f() = 9223372036854775808

function parse() end

ERROR: LoadError: error in method definition: function Base.parse must be explicitly imported to be extended

The problem goes away if the f definition is removed, or if it doesn't return a huge integer.

Also the same issue: JuliaCI/Coverage.jl#54
