Ampersand produces </HIML_ERB_TAG>

[sakuro]

Using safe navigation operator (&.), Himl 0.1.1 produces unexpected </HIML_ERB_TAG>.

without &.

require 'himl'

template = '<%= @x.nil? ? nil : @x.to_f %>'
@x = 1r/3

parser = Himl::Parser.new
puts parser.call(template).to_erb

produces

<%= @x.nil? ? '' : @x.to_f %>

with &.

require 'himl'

template = '<%= @x&.to_f %>'
@x = 1r/3

parser = Himl::Parser.new
puts parser.call(template).to_erb

produces

</HIML_ERB_TAG>
<%= @x&.to_f %>

[sakuro]

Simpler one.

parser.call('<% x & y %>').to_erb

produces

</HIML_ERB_TAG>
<% x & y %>

Or, syntactically incorrect but

parser.call('<% & %>').to_erb

produces

</HIML_ERB_TAG>
<% & %>

[sakuro]

<% < %> works similarly.
