Feature #17520: Allow symbols starting with number, e.g. :2_weeks

• Status: Feedback

For instance:

p({ 2_weeks: 1 })

results in:

a.rb:1: trailing `_' in number
p({ 2_weeks: 1 })
a.rb:1: syntax error, unexpected local variable or method, expecting =>
p({ 2_weeks: 1 })

and

p({ :2_weeks => 1 })

results in:

a.rb:1: trailing `_' in number
p({ :2_weeks => 1 })
a.rb:1: syntax error, unexpected integer literal, expecting literal content or terminator or tSTRING_DBEG or tSTRING_DVAR

I'm not sure if it's doable as ruby thinks I'm writing a number, just wondering if that could be possible to start a symbol with a number

(I know { "2_weeks": 1 } works, that's what I'm using instead)

You may not know that:

p({ '2_weeks': 1 })
# => prints {:"2_weeks"=>1}

Such symbols being quite rare, I believe this solution should be enough.
