@carlosmiei can you make a quick approval for this?

@carlosmiei can you give me a hand here?

[ value, params ] = this.handleOptionAndParams (...)
if (condition) {
    [ value, params ] = this.handleOptionAndParams (...)

is transpiled into c# like:

var valueparametersVariable = this.handleOptionAndParams(...);
value = ((IList<object>)valueparametersVariable)[0];
parameters = ((IList<object>)valueparametersVariable)[1];

if (...) {
   var valueparametersVariable = this.handleOptionAndParams(...);

so as you see, var is declared two times, in lower scope too, causing errors in build: https://app.travis-ci.com/github/ccxt/ccxt/builds/270262306#L2672

and I couldn't find where that specific transpilation is being done in chsarp-transpiler.ts to amend

@carlosmiei this should be ready after travis finishes
