Issue #17520 has been updated by marcandre (Marc-Andre Lafortune).
Status changed from Open to Feedback
You may not know that:
```ruby
p({ '2_weeks': 1 })
# => prints {:"2_weeks"=>1}
```
Such symbols being quite rare, I believe this solution should be enough.

Bug #17520: Allow symbols starting with number, e.g. :2_weeks
https://bugs.ruby-lang.org/issues/17520#change-89836
* Author: dorianmariefr (Dorian Mari薊
* Status: Feedback
* Priority: Normal
* ruby -v: ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
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)
