I wonder, if expression
a :== 5
having right to live? Since there is no restrictions on binary selectors length, a #:= followed by any binary char(s) can be treated as binary selector instead of assignment, followed by syntax error.
What you think?
One more thing which i discovered in current parser:
#$A inspect
returns a character, not symbol. Is this correct to the syntaxt rules?
If not, what symbol it should be #A or # '$A' instead?

It should be a syntax error, period. Like
a :== 5
should.
One idea I was toying with was to allow . in binary selectors, except for the special #. of course; this goes along with the idea of considering . to be a statement terminator only if not followed by whitespace (avoiding the unintuitive behavior of {1.0.2.0}). For example,
1..5 do: [ :i | Transcript show: i ]
