Duplicate variable names with 'variables' and others

[ash0080]

In test example,

methodArgs: {
    last: {__variable__: 'last'}
  },
variables: {
    last: ''
  },
types: {
    last: 'LAST'
  },

output: body: 'query test($last: LAST!) {\n    testMethod(last: $last, last: $last){\n    id\n\n  }\n  }',

don't know why passing a value in variables, it is useless. cuz variable's value is passed from outside of the graphql-tag, it only defines a name here. doc

actually, I don't think variables should be an object, It should be a keys array, cuz, it only define the variable types

so __variable__ is useless too, cuz we alway need define variable names with a named operation

now, the 'methodArgs', 'variables', 'types' design looks superfluous and not easy to use
maybe you should plan well

if keeping the variables still accept an object, I think the key:value <--- value should be an TYPE definition

I guess maybe you want the variable accept a default value? but seems it not work as expect
