[jira] [Commented] (GROOVY-8882) CS: Loop over elements of String has different element type

["Paul King (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-8882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16693900#comment-16693900 ] 

Paul King commented on GROOVY-8882:
-----------------------------------

Seems like an inconsistency to me but has been that way since the early days of CS:
https://github.com/apache/groovy/blob/master/src/main/java/org/codehaus/groovy/transform/stc/StaticTypeCheckingVisitor.java#L1934

>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 2.4.15
>            Reporter: Eric Milles
>            Priority: Minor

> When the method below is executed as-is, the output is "java.lang.String" x3.  When {{@CompileStatic}} is uncommented, the output is "java.lang.Character" x3.  Is it possible to have dynamic groovy match the static compilation result?
> {code:groovy}
> //@groovy.transform.CompileStatic
> void meth() {
>   for (c in 'abc')
>     println c.class.name
> }
> {code}
> Similarly, {{'abc'*.anything}} applies to Strings of length one instead of Characters.  Although, spread-dot is not supported against strings under static compilation.  Is it possible to add that support?
