Spaces between opening parentheses of method and 1. argument raises error.

bug:

Invoking a method where there is at least one space before the 1. argument, raises an error.

expect:

It should simply ignore spaces between the opening parentheses of the called method and the start of the 1. argument.

code: input

let name = "name"
echo $len( $name)

actual: output

ion: expansion error: Variable does not exist

expect: output
