Bug #18038: Invalid interpolation in heredocs
https://bugs.ruby-lang.org/issues/18038
* Author: maciej.mensfeld (Maciej Mensfeld)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-linux]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
Given code as followed:
``` ruby
var = 1
v1 = <<~CMD
something
#{"/#{var}"}
CMD
v2 = <<~CMD
something
#{other = "/#{var}"}
CMD
v3 = <<~CMD
something
#{("/#{var}")}
CMD
p v1
p v2
p v3
p v1 == v2
p v2 == v3
```
result of running this:
```ruby
"something\n/\n"
"something\n/1\n"
"something\n/\n"
false
false
```
I would expect both heredocs to return the same value for all the cases. It seems the `other` variable assignment should be irrelevant but only with it the value "1" is present.
