[Pharo-users] Too many parenthesis - a matter of syntax

[Kasper Osterbye]

Cheers all

I have noticed that I often ends up with quite a number of nested expressions, 
for example:

(((json at: 'tree') 
        select: [ :e | (e at: 'type') = ‘blob' ]) 
                collect: [:e | Path from: (e at: 'path')])
                        select: [ :p | p segments last 
                                in: [ :name | (name endsWith: '.md') | (name 
endsWith: '.mic') ] ]

What kind of proposals (if any) have been for a different syntax which could 
give a more streamlined syntax?

My own thinking has been around an alternative to the cascade semicolon. What 
symbol to use does not matter for me, but something like
json at: ‘tree' º
        select: [ :e | ((e at: 'type') = 'blob’)]º
        collect: [:e | Path from: (e at: 'path’)]º
        select: [ :p | p segments last 
                in: [ :name | (name endsWith: '.md') | (name endsWith: '.mic') 
] ]

Basically, a send the right hand expression to the result of the left hand 
expression.

Has anyone ever tried this, or is it just one of the many small annoyances best 
left alone?

Best,
