chained methods do no parse correctly if . is separated from call

[sredrv]

Describe the feature

V currently supports, method chaining in single-line, as below.

	mut s:= 'aAabBc'
	s = s.camel_to_snake().to_lower().to_upper()

I want V to support, methods specified on more than one line:

	mut s:= 'aAabBc'
	s = s.  camel_to_snake().
                 to_lower().
                 to_upper()

Use Case

Readability issue, when more custom built methods are used.

Proposed Solution

V language parser needs to be enhanced

The code works as expected if you move the .s to the front of each call (no spaces between), as in

        mut s:= 'aAabBc'
        s = s   .camel_to_snake()
                .to_lower()
                .to_upper()
        println(s)

which gives the output

A_AAB_BC

Now, whether or not it should be considered an error with the . at the end, I don't know.

At the very least, the error messages could be cleaned up a LOT, to better convey what's wrong. Here's what you get currently:
