Has any programming language/compiler implemented pronoun like
constructs? For example:


                if variable_with_long_name == '2 ,
{ do this; }
if it == '3 , # equivalent to: variable_with_long_name == '3
{ do that }




Alternatively or in addition, elision (automatic scope changing),
for example:


if variable_with_long_name == '2 ,
{ do this; }
if == '3 , # equivalent to: variable_with_long_name == '3
{ do that }


Would it be a good idea? I don't think that it'd be too difficult to
implement in my project . . .


[I can think of some examples. Lisp LET (typically implemented as an
anonymous procedure) permits you to assign names to expressions for very
limited scopes. Cobol lets you elide comparison operands, something like
IF FOO-BAR LESS THAN 12 OR GREATER THAN 42 THEN ... -John]
