During a recent update[^1] the static optimizer was taught to convert the
Mexico ≥, ≤, and ≠ ops to their Texas alternatives.
It was later pointed out[^2] that this aliasing is stronger than originally
intended:
multi sub infix:«<=» ( Str $, Str $ --> 'Str' ) {}
say 'f' <= 'f'; # Str
say 'f' ≤ 'f'; # Str
It doesn't work the other way around though: defining own ≤ op won't make <=
use it and
these three ops are probably the only ones for which this kind of thing happens.
I removed[^3] this kind of aliasing, for now.
The RFC is: should this kind of aliasing be done for *all* Mexico ops?
- The Mexico name is the one that is implemented as an alias to the Texas
name
- Defining a lexical Texas op makes Mexico ops use that lexical for free
- Defining a lexical Mexico op does NOT make Texas alternatives use it for
free
